Ready.
Feeding a baby is one of the most natural things in the world — and also one of the most unexpectedly challenging. Every day, new parents sit in dimly lit rooms at 3 a.m., unsure whether their baby is latching correctly, whether they have enough milk, or whether the pain they're feeling is normal. What many of them need in that moment is not a prescription or a diagnosis. What they need is someone who knows — who can observe, educate, reassure, and guide them through one of the most vulnerable and formative experiences of their lives. That is the work of a lactation specialist.
This is your first lesson in the DNT Network Lactation Specialist Certification Course, and it is designed to give you a clear, grounded foundation for everything that follows. We will introduce you to the field of lactation support, explore who lactation specialists are and what they do, explain how this course is structured and what you will gain from it, and show you how your training connects to the broader landscape of professional lactation care — including, for those interested, a future pathway toward the IBCLC credential.
You do not need a medical background to begin this course. You need curiosity, a commitment to learning, and a genuine desire to support families. We will build the rest together.
How to Use This Lesson
Read at your own pace, or listen with the Read Aloud controls above. Along the way you will find short fictional examples (they are labeled, and none are real clients), three videos, and five optional Activities that let you practice what you just read. Near the end you can download a one-page reference handout, and a ten-question quiz helps you check what stuck. Nothing here is a trap. It is all there to help you learn.
The early days of breastfeeding can be full of uncertainty — skilled lactation support helps families find their footing with confidence.
Section 1
Why Lactation Support Matters
Before we talk about what lactation specialists do, it helps to understand why this kind of support is so important in the first place.
The evidence on breastfeeding outcomes is substantial and consistent. Decades of research across high-income and low-income countries have documented benefits for both infants and mothers, ranging from reduced rates of infection and overweight in children to lower maternal risk of breast cancer and type 2 diabetes. A landmark 2016 analysis published in The Lancet concluded that improving breastfeeding rates globally could prevent over 820,000 child deaths each year — and that the economic cost of suboptimal breastfeeding totals approximately $302 billion annually in lost productivity and increased health care costs (Rollins et al., 2016).
What does this have to do with you? A great deal. Because the same research that documents breastfeeding's benefits also makes something else clear: most people who stop breastfeeding earlier than they intended to do not stop because they wanted to. They stop because they ran into problems — pain, low milk supply concerns, latch difficulties, lack of confidence — and they did not have access to skilled, timely support at the moment they needed it most (Rollins et al., 2016).
That is the gap lactation specialists fill. Trained lactation supporters are not a luxury. They are part of the infrastructure that makes it possible for families to reach their own feeding goals.
What That Research Means in Plain English
Let's slow down and unpack it. The Lancet Breastfeeding Series brought together researchers from many countries. They gathered a large amount of published evidence on breastfeeding and then estimated what could change if more families were able to feed the way they hoped to. The World Health Organization and UNICEF recommend starting breastfeeding in the first hour after birth, feeding only breast milk for about the first six months, and continuing breastfeeding alongside other foods up to two years or beyond.
Two cautions are worth carrying with you. First, much of this evidence is observational. Researchers followed what happened in families who made different choices, because it would not be ethical to randomly assign babies to different feeding methods. Observational studies can show strong links, but they cannot prove cause on their own. Families who breastfeed longer may also differ in income, health, or the support they have at home.
Second, the big numbers describe whole populations. They explain why support matters at a large scale. They do not predict what will happen for one baby, and you should never use them to pressure a parent. Your job is to help families reach their own goals, not to judge their choices.
Fictional Educational Example Not a real client
Rosa is 34 weeks pregnant with her first baby and plans to return to work when the baby is twelve weeks old. At a prenatal class, she says quietly, “My mother told me I probably won't make enough milk, so why bother?” The class is led by Camille, a lactation specialist.
Camille: “That sounds like a worry you've been carrying. What made your mother say that?”
Rosa: “She had a hard time and nobody helped her.”
Camille: “I'm sorry she went through that. Here is something hopeful. Most parents can make enough milk, and good help early on makes a real difference. Would it help to plan now who you can call in the first week?”
Why this works: Camille listens first, acknowledges the story behind the worry, shares accurate information without promising an outcome, and offers a plan. She does not predict Rosa's milk supply, because no one can do that before the baby is born. Rosa's mother's experience is exactly the gap the research describes: the problem was missing support, not missing desire.
A Note on Language
Throughout this course, you will see the terms breastfeeding and chestfeeding used. Chestfeeding is a term used by many transgender men, nonbinary individuals, and gender-expansive parents who produce milk and feed their infants at the chest. Both terms refer to the same physiological process, and both populations benefit equally from skilled lactation support. Inclusive language is part of providing high-quality, respectful care.
Conversations about feeding often begin during pregnancy, long before the baby arrives.

Myth or Fact?
Why this helps: Misunderstandings about breastfeeding are common, and you will hear them from families, relatives, and even colleagues. Sorting myth from fact now makes it easier to respond calmly later.

What Is a Lactation Specialist?
A lactation specialist is a trained professional who provides evidence-based education, guidance, and supportive care to pregnant individuals, new parents, and families navigating breastfeeding and chestfeeding. The role is practical, relational, and deeply educational.
Lactation specialists work in a wide range of settings: private practice, hospital systems, birth centers, home visiting programs, public health agencies, insurance-supported care platforms, and community-based roles. They may work independently, as part of a doula or newborn care practice, or as a complementary support provider within a clinical team.
The title "lactation specialist" describes an entry-level trained professional credential — one that is grounded in solid lactation knowledge, communication skills, and practical support skills. It is not a medical license, and it does not carry diagnostic authority. What it does carry is a meaningful professional foundation for helping families in some of their most critical early weeks.
What a Typical Week Might Look Like
Because lactation specialists work in so many places, no two weeks look the same. On Monday you might lead a prenatal feeding class. On Wednesday you might visit a family at home. On Thursday you might answer a text from a worried parent, and on Friday you might join a team meeting at a birth center.
What stays the same is the approach. You listen first. You observe carefully. You teach clearly. And you know when to hand a concern to someone else.
In Practice
Nina is a first-time mother whose baby is three days old. She is experiencing nipple pain, worries that her baby is not getting enough milk, and feels increasingly discouraged every time feeding becomes stressful. Her lactation specialist, Jordan, does not diagnose medical conditions or replace a medical provider — but Jordan is trained to observe a feeding session carefully, identify positioning and latch patterns that may be contributing to the pain, offer evidence-based education about infant feeding cues and normal milk supply development, provide reassurance grounded in what the research actually shows, and clearly explain when it would be appropriate for Nina to follow up with her pediatrician or OB.
After one supported session and two follow-up check-ins over the following week, Nina reports feeling significantly more confident. She understands what she is seeing when she feeds her baby. She knows what normal looks like — and what to watch for. She is no longer guessing alone in the dark.
This is what skilled lactation support looks like in practice.
Video
Is Your Baby Getting Enough Milk?
Nina's worry in the story above is one of the most common concerns parents bring to lactation support. This short video explains how parents can tell whether a baby is getting enough milk. As you watch, think about how you would explain the same ideas to a worried parent in your own words.

Observing a feeding closely is one of the most important skills a lactation specialist builds.
Lactation specialists combine clinical knowledge with skilled, person-centered communication — meeting families exactly where they are.
What Lactation Specialists Do
- Provide antenatal lactation education to expectant parents during pregnancy
- Observe and assess feedings to identify latch, positioning, and transfer concerns
- Offer evidence-based guidance on milk supply, feeding frequency, and infant output
- Educate families on normal infant feeding behavior and developmental patterns
- Support parents through common challenges such as engorgement, nipple soreness, and early return to work
- Provide pumping guidance, including output expectations and equipment use
- Discuss options and information around combination feeding, supplementation, and weaning
- Practice skilled communication that centers the parent's goals, values, and circumstances
- Recognize when a concern is outside their scope and refer appropriately to clinical care
If you look closely, the whole list rests on four habits: listen, observe, teach, and refer. When Jordan sat with Nina, all four showed up. Jordan listened to her worries, watched the feeding, taught her what normal looks like, and explained when to call her pediatrician or OB. As you move through this course, you will keep returning to these four habits.
Section 3Scope of Practice: What Lactation Specialists Do and Don't Do
Understanding your scope of practice is one of the most important things you will develop as a lactation specialist. It protects the families you serve, preserves the integrity of your role, and ensures that you are practicing in a way that is both ethical and effective.
Lactation specialists work within a non-diagnostic, educational, and supportive scope. This means that your role is to inform, observe, educate, and guide — not to diagnose medical conditions, prescribe treatments, or replace the care of physicians, midwives, nurses, or other licensed clinical providers.
| Within a Lactation Specialist's Scope | Outside a Lactation Specialist's Scope |
|---|---|
| Observing and assessing a feeding session | Diagnosing medical conditions (e.g., tongue-tie, mastitis) |
| Providing evidence-based education about latch, positioning, and milk supply | Prescribing medications or treatments |
| Discussing normal vs. concerning infant feeding patterns | Recommending or adjusting medical care without clinical authority |
| Offering emotional support and practical guidance | Providing diagnoses based on clinical assessment |
| Explaining the WHO Code on the marketing of breast milk substitutes | Acting outside the policies and ethical standards of your certifying organization |
| Referring appropriately to physicians, IBCLCs, or other specialists | Replacing the role of a licensed clinical provider |
Scope of practice is not a limitation — it is a source of clarity and confidence. When you know your lane, you can work within it skillfully, and you know exactly when to call in someone who can do more. Families are best served when every provider on their team understands their role and communicates effectively across it.
Why These Boundaries Exist
Boundaries exist to protect families. A hot, sore breast, a fever, or a baby who feeds poorly can look like a simple feeding problem and still be something else. A person trained in lactation education is not trained to tell the difference. The safest and most helpful thing you can do is describe what you see, share what is normal, and connect the family with someone who can examine and treat.
Fictional Educational Example Not a real client
Tasha is a postpartum doula who recently earned her CLS credential. During a home visit, her client Imani, six days postpartum, says her left breast feels hot and sore. “I think I have a fever,” Imani says. “Is this mastitis? Should I just pump more?”
Tasha: “I can hear how uncomfortable you are. I can't tell you what this is, because that takes a medical exam. Heat, soreness, and a possible fever are things your provider needs to hear about today. Do you have a thermometer?”
Imani: “Yes. It says 101.3.”
Tasha: “Thank you. Please call your midwife or doctor now. I'll stay with you and help you write down your symptoms. Once you've talked with them, I'm glad to help with feeding.”
Why this works: Tasha did not name the condition, did not suggest a treatment, and did not wait. She showed empathy, gathered simple facts, and referred the same day. She also kept her relationship with Imani going by offering feeding help afterward. That is referral as a professional skill.
Important: Referral is a Skill
Knowing when to refer is not a sign of inadequacy — it is evidence of professional competence. A lactation specialist who can identify that an infant may have an oral function concern, document their observations clearly, and communicate effectively with the family's pediatrician is providing an enormous service. You will learn how to do this well throughout this course.
Words That Keep You in Scope
The way you phrase things matters. Here are a few starting points you can adapt to your own voice:
- “I'm not able to diagnose that, but here is what I'm noticing.”
- “This is a good question for your provider. Would you like help writing it down?”
- “What I can tell you is what research says about normal feeding patterns.”
- “I'd like you to call your provider today, and I can help you explain what we saw.”
Gentle, careful observation helps you describe what you see without guessing at a diagnosis.
Activity
Section 4
Scope-of-Practice Sorter
Why this helps: Scope is easier to understand when you apply it to real situations. Deciding quickly whether an action is yours to take builds the judgment you will use every day.
For each action, choose “Within my scope” or “Outside my scope.” Remember that referring a family to a provider is within your scope. This activity is optional.
Where Lactation Specialists Fit in the Larger Care Picture
Lactation specialists do not work in isolation. You are part of a broader community of care that supports families through pregnancy, birth, and the postpartum period. Understanding where you fit in this picture — and who your colleagues are — helps you collaborate effectively and serve families more fully.
The research is clear that families benefit most when breastfeeding support comes from multiple directions: skilled clinical providers, trained community supporters, peer counselors, and informed family members all play a role. A 2014 framework from researchers at the University of Dundee found that quality maternal and newborn care — including breastfeeding support — requires a system-level shift toward preventive and supportive care delivered by well-trained providers across clinical and community settings (Renfrew et al., 2014).
Lactation specialists bridge clinical and community-based care. You may work alongside or in referral relationships with:
- OBs, midwives, and family physicians who provide medical care during and after pregnancy
- Pediatricians and neonatologists who monitor infant health and growth
- IBCLCs (International Board Certified Lactation Consultants), who provide advanced clinical lactation care
- Labor and delivery nurses and postpartum nurses who offer in-hospital support
- Doulas, who provide continuous labor and postpartum support
- Newborn care specialists, who support families in the early days and weeks
- Peer counselors, who offer lived-experience-based support within communities
- Public health workers and home visiting nurses, who reach families in community settings
Each of these professionals has a distinct scope and a distinct role. Knowing who does what — and how to communicate effectively across disciplines — is a core skill you will build in this course.
Fictional Educational Example Not a real client
Keisha is a CLS who supports a birth center's postpartum program. One morning, Andre calls. His partner Simone is four days postpartum, and the baby “barely woke up to eat” overnight.
Keisha: “Thank you for calling, Andre. How many wet diapers has the baby had in the last 24 hours?”
Andre: “I think just two.”
Keisha: “That's fewer than I'd expect for day four, and together with the sleepiness, I'd like the baby's pediatric provider to hear about it today. Please call their office now. If the baby is very hard to wake or you feel worried at any point, go to urgent care or call 911. I'll check in with you this afternoon.”
Why this works: Keisha does not diagnose. She recognizes a pattern that needs a clinician, communicates it clearly and calmly, and follows up. Each person on this family's team has a role: the pediatric provider examines the baby, and Keisha supports the family and makes sure the right person is reached.
Many families first meet lactation support in a hospital or birth center, alongside nurses and physicians.

The Lactation Specialist vs. the IBCLC: Understanding the Difference
One of the most common questions new students ask is: How is a lactation specialist different from an IBCLC? This is a great question, and it is worth understanding clearly — both because it defines your own role and because it helps you explain your credential to families and colleagues.
| Credential | Lactation Specialist (CLS) | IBCLC |
|---|---|---|
| Full title | Certified Lactation Specialist | International Board Certified Lactation Consultant |
| Level | Entry-level trained professional credential | Advanced clinical credential |
| Credential awarded by | DNT Network | IBLCE (International Board of Lactation Consultant Examiners) |
| Scope | Education, support, latch guidance, non-diagnostic care | Full clinical lactation management, including complex cases and diagnostic assessment |
| Education required | Lactation-specific training (95+ hrs via DNT Network) | Health sciences prerequisites + 90 hrs of lactation-specific education + 300–1,000 clinical hours (depending on pathway) + board exam |
| Exam | Course completion and assessment | IBLCE board certification exam |
| Who earns it | Doulas, birth workers, nurses, peer counselors, community health workers, physicians, and others | Nurses, midwives, physicians, dietitians, and others with qualifying health science backgrounds and clinical hours |
To put it simply: a lactation specialist is a trained, credentialed professional who provides education and support within a clearly defined non-diagnostic scope. An IBCLC is a higher-level clinical credential that requires significantly more training, health science prerequisites, supervised clinical hours, and a rigorous board examination.
Both credentials matter. Both fill real needs in the care landscape. And as you will see in the next section, earning your Certified Lactation Specialist (CLS) credential through DNT Network is not only valuable in its own right — it can also serve as a meaningful stepping stone if you later choose to pursue the IBCLC.
Explaining Your Credential to a Family
Parents will sometimes ask what your letters mean. A short, honest answer builds trust. You might say:
Try Saying
“I'm a Certified Lactation Specialist. I teach families about feeding, watch feedings and help with positioning, and offer encouragement. If something needs medical care, or a more advanced lactation evaluation, I'll help you connect with the right provider.”
Notice what this does. It tells the family what you can offer, and it names the limits without apology. Families tend to trust professionals who are clear about both.
Whether a family sees a CLS or an IBCLC, they deserve clear, kind, and accurate support.

How the Learning Is Built
The course moves from simple to complex. The lessons that follow begin with the basics: how the body makes milk, how babies grow, and how nutrition supports lactation. From there you will practice positioning, latch, pumping, and care planning. You will then work through common challenges for parents and infants, build communication and cultural sensitivity skills, study ethics and public health, and finish with evidence-based practice and exam orientation. Each new idea has something earlier to rest on, so you are never asked to jump in at the deep end.
What the Course Covers
The curriculum is built around the knowledge areas, skills, and competencies that lactation specialists need to support families effectively. The content progresses from foundational concepts to more nuanced clinical language and real-world application. Core content areas include:
- Anatomy and physiology of lactation — how the breast makes, stores, and releases milk; hormonal regulation of milk production; how milk supply is established and sustained
- Infant anatomy and feeding physiology — how infants suck, swallow, and breathe; normal oral motor function; how anatomical variations may affect feeding
- Normal infant feeding behavior — hunger cues, feeding frequency, normal patterns by age and developmental stage
- Latch and positioning — evidence-based techniques, how to observe and assess a feeding, and how to guide parents through adjustments
- Milk supply: assessment and support — understanding perceived vs. actual low milk supply, how to support building and maintaining supply, and when to refer
- Common breastfeeding challenges — engorgement, sore nipples, mastitis, plugged ducts, thrush, slow weight gain, and more
- Special circumstances — premature infants, multiple births, infants with special needs, parents returning to work, LGBTQ+ families, and more
- Pumping and milk expression — hand expression, pump selection and use, milk storage, and return-to-work planning
- Communication skills (5 hours) — this required component fulfills the IBLCE requirement for 5 hours of communication skills education; it covers counseling frameworks, motivational interviewing, active listening, navigating difficult conversations, and culturally responsive communication
- WHO Code education (2 hours) — this fulfills the IBLCE requirement for 2 hours of education on the International Code of Marketing of Breast-Milk Substitutes; it covers the history, intent, and practical application of the WHO Code in lactation support practice
- Evidence-based practice and research literacy — how to read and apply research in lactation practice; understanding levels of evidence; introducing key professional resources
- Scope of practice and professional ethics — boundaries of the lactation specialist role, professional standards, and ethical practice
- Referral and interprofessional collaboration — when and how to refer; communicating effectively with clinical colleagues
Latch and positioning are among the first hands-on skills you will learn.

Attaching Your Baby at the Breast
Latch and positioning are core topics in this course. This video shows how a baby attaches at the breast. You do not need to memorize anything yet. Notice how the parent and baby are positioned, since you will study these details in later lessons.
Video from Global Health Media Project. If the video does not load, watch it on YouTube.
Key Terms in Plain English
You will meet many new words in this course. Here are a few you will see right away:
- Latch: how the baby's mouth attaches to the breast or chest to feed.
- Milk transfer: how much milk the baby actually removes from the breast during a feeding.
- Perceived low milk supply: when a parent feels there is not enough milk, whether or not the supply is actually low. It is very common, and it deserves a careful, kind response.
- Scope of practice: the tasks your role and credential allow you to do.
- Referral: connecting a family with another qualified professional who can help with something outside your scope.
Lactation support is really about the bond between a parent and a baby, and the confidence to nurture it.
A Note on the WHO Code
The International Code of Marketing of Breast-Milk Substitutes — commonly called the WHO Code — is a global framework adopted by the World Health Organization in 1981 to protect breastfeeding by regulating the marketing of formula, bottles, and nipples. Understanding the WHO Code is not only required for IBCLC exam candidates; it is foundational knowledge for any professional working in the lactation space. This course includes 2 hours of dedicated WHO Code education, meeting IBLCE's requirement and ensuring that you understand how commercial marketing influences infant feeding decisions — and how to have informed, ethical conversations with the families you serve.
Recognition, Reach, and Why DNT Network Is Different
Earning a professional credential is only as valuable as the recognition it carries. The DNT Network Lactation Specialist Certification is designed to be professionally meaningful — not just as a learning achievement, but as a credential that opens doors and demonstrates real competence.
Where DNT Network Is Accepted and Recognized
DNT Network's CLS credential is accepted and recognized across all 50 U.S. states and internationally. Within the United States, it is recognized by state Medicaid programs, Carrot, Maven Clinic, major insurance plans, hospitals, birth centers, and agencies that contract with lactation support providers. For doulas, newborn care specialists, and other birth workers who serve families in a professional capacity, holding the CLS credential can directly affect your ability to be reimbursed, contracted, or hired in settings that require verified lactation training.
What Sets This Program Apart
- No renewal fees, no expiration: Unlike many professional certifications, DNT Network's CLS credential includes lifetime access with no ongoing renewal costs or hidden fees. What you earn is yours to keep.
- Built for real-world providers: The curriculum was developed with working birth and health professionals in mind — not abstract learners in controlled environments. Content is practical, applied, and immediately useful in the settings where you actually work.
- Accessible to all education levels: You do not need a nursing degree or medical background to succeed in this program. It is genuinely designed for learners at all levels, and it builds from simple to more complex concepts in a logical, scaffolded way.
- IBCLC-exam-aligned content: The 95+ hours of content, including the 5 hours of required communication skills training and 2 hours of WHO Code education, are structured to meet IBLCE's education requirements — making this course meaningful for students who may later pursue the board exam.
- Dedicated teacher support: Students have access to responsive teacher support throughout the course — not just a course portal with no human connection.
- Self-paced with flexible access: Life does not stop when you enroll. The course is 100% self-paced, and most students complete it in about 5 weeks, though you have the flexibility to go at the pace that works for your life and schedule.
What a Credential Looks Like in Everyday Work
Fictional Educational Example Not a real client
Elena is a newborn care specialist applying to work with a family-care agency. During her interview, the coordinator asks whether she has lactation training the agency can verify.
Coordinator: “Many of our families ask about feeding support. Do you have lactation training we can confirm?”
Elena: “Yes. I completed more than 95 hours of lactation education through DNT Network and hold the Certified Lactation Specialist credential. I can send you my certificate.”
Why this matters: A clear, verifiable credential turns “I know a bit about breastfeeding” into something an employer, agency, or insurer can check. It also tells families that you completed structured, evidence-based training.
A recognized credential helps families and employers trust the care you offer.
This Course as a Pathway Toward the IBCLC
For students who are interested in eventually pursuing the International Board Certified Lactation Consultant (IBCLC) credential, this section is especially important. While the DNT Network Lactation Specialist Certification is a complete and valuable credential on its own, it is also thoughtfully designed to support students who may later want to pursue the IBCLC — the highest credential in the lactation profession.
What the IBCLC Requires
The IBCLC exam is administered by the International Board of Lactation Consultant Examiners (IBLCE) and is recognized globally. To sit for the exam, candidates must meet specific education requirements that include:
- A specified number of health science prerequisite courses (anatomy, physiology, nutrition, psychology, sociology, and related subjects)
- 90 hours of lactation-specific education, including 5 hours of communication skills and 2 hours of WHO Code education
- Clinical experience hours — ranging from 300 to 1,000 hours of supervised lactation-specific clinical experience, depending on which eligibility pathway the candidate uses
- Passing score on the IBLCE board examination
These requirements ensure that IBCLCs have a rigorous, clinically grounded foundation for advanced lactation practice. The IBCLC is a demanding credential, and it is designed to be.
How This Course Fits In
The DNT Network Lactation Specialist Certification Course is aligned with the IBLCE education requirements in meaningful ways:
IBLCE-Aligned Education Hours
This course provides 95+ hours of lactation-specific education, including the 5 required hours of communication skills training and 2 required hours of WHO Code education specified by IBLCE. Students who complete this course will have met the lactation-specific education hour requirement for the IBCLC exam pathway.
Note: Meeting education hour requirements is one component of IBCLC eligibility. Students who intend to pursue the IBCLC should review current IBLCE eligibility requirements directly at iblce.org, as requirements may be updated over time.
Beyond meeting the formal hour requirement, this course builds the kind of foundational knowledge that makes IBCLC exam preparation more effective. Students who complete the DNT Network program will enter advanced study with:
- A solid understanding of lactation anatomy, physiology, and clinical language
- Familiarity with evidence-based breastfeeding research and how to apply it in practice
- Fluency with communication frameworks and counseling approaches emphasized in the IBCLC exam
- Working knowledge of the WHO Code and its application
- Practical experience supporting families, which is foundational to accruing the clinical hours required for IBCLC eligibility
- The confidence that comes from having already successfully completed a rigorous lactation training program
Fictional Educational Example Not a real client
Carlos is a registered nurse with six years on a postpartum unit. He is thinking about becoming an IBCLC and writes to teacher support before enrolling.
Carlos: “If I finish this course, can I go straight to the IBCLC exam?”
Teacher support: “Completing the course covers the lactation-specific education hours, including the communication skills and WHO Code hours. The exam also requires health science education, supervised clinical hours, and an application. Because IBLCE can update its rules, please check iblce.org for the current requirements. Would you like help making a checklist?”
Why this works: The answer is honest about what the course does and does not cover. It does not promise eligibility, and it points Carlos to the official source. Being clear about the next steps is part of ethical professional communication.
The CLS Credential: Value Beyond the Pathway
It is important to say clearly: you do not need to pursue the IBCLC for your CLS credential to be professionally meaningful. Many lactation specialists build rewarding, impactful careers entirely within the CLS scope — supporting hundreds or thousands of families across a career without ever sitting for the IBCLC board exam.
The CLS credential demonstrates entry-level professional competence in lactation support. It signals to families, employers, and colleagues that you have completed structured, evidence-based training and are prepared to serve families responsibly. For doulas, newborn care specialists, peer counselors, and community health workers, it is often exactly the credential that is needed — not a stepping stone, but the destination.
- Accepted across all 50 states and internationally
- Recognized by Medicaid, insurance plans, hospitals, and birth centers
- Recognized by Carrot and Maven Clinic
- Demonstrates commitment and professional competence to families and employers
- Supports reimbursement and contracting in many professional settings
One Possible Path Forward
For students interested in eventual IBCLC pursuit, here is how the journey often unfolds:
01
Complete DNT Network CLS
Build your lactation foundation. Earn your CLS credential. Begin supporting families.
02
Gain Clinical Experience
Accumulate supervised lactation support hours in clinical or community settings.
03
Complete Prerequisite Courses
Fulfill IBLCE's health science education requirements (anatomy, physiology, nutrition, etc.).
04
Apply to Sit for IBLCE Exam
Confirm eligibility, submit your application, and prepare for the board examination.
05
Pass the IBLCE Exam
Earn the IBCLC credential and practice at the advanced clinical level.
Your DNT Network training is the foundation on which everything else builds. Students who come to advanced lactation study with a strong working knowledge base — like the one you are building now — are better prepared, more confident, and better equipped to succeed on the path toward the IBCLC exam.
Many IBCLC candidates begin their journey by supporting families, one feeding at a time.

Evidence-Based Practice: Why It Matters for Lactation Support
You will hear the phrase evidence-based practice throughout this course. It is worth taking a moment to explain what that actually means — because it is not just a buzzword. It is the foundation of responsible professional practice in any health-related field.
Evidence-based practice means that the guidance and support you offer families is grounded in the best available research, integrated with clinical expertise and the values and preferences of the individual you are supporting. It means that when you tell a parent that frequent feeding in the first days is normal and important for establishing milk supply, you can connect that statement to a body of research — not just tradition or anecdote.
In lactation support, this matters enormously. New parents are often flooded with conflicting information from well-meaning family members, social media, outdated books, and popular culture. Your job is to cut through the noise with clear, accurate, research-informed guidance.
A 2022 systematic review by Chesnel, Healy, and McNeill found that the experiences and beliefs of trained breastfeeding support providers significantly shaped how they delivered support in practice — for better or worse. Providers who had strong, evidence-grounded foundations tended to provide more consistent, effective support, while those relying primarily on personal experience or informal knowledge showed more variability in the quality of care they offered (Chesnel et al., 2022). This finding underscores why structured, evidence-based training — exactly the kind you are undertaking — matters not just for what you know, but for how you practice.
Reading Research Like a Practitioner
Not all evidence carries the same weight. Here is a simple way to think about it, from stronger to weaker for answering most questions about what works:
- Systematic reviews gather and combine many studies on one question.
- Randomized trials assign people by chance to different approaches, which helps show cause.
- Observational studies follow people in real life, which is useful but can be affected by other factors.
- Expert opinion and personal experience can offer ideas and context, but they are the easiest to get wrong.
None of these is useless. They answer different questions. One more point about the Chesnel review: it looked at qualitative studies, which collect people's experiences in their own words. That means it helps us understand how providers' beliefs shaped their support. It does not tell us how much milk babies received or how long families breastfed. Knowing what a study can and cannot show is part of using it honestly.
What "Evidence-Based" Looks Like in Practice
It looks like this: A parent asks you whether she needs to wean because she has a sinus infection and is taking amoxicillin. An evidence-based lactation specialist does not guess or go by what they personally did. They know — because they have been trained — that the vast majority of common antibiotics are compatible with breastfeeding and that continuing to nurse while ill is generally safe and beneficial for the baby. They explain the evidence clearly, encourage the parent to confirm with their prescribing provider, and offer reassurance grounded in fact rather than fear.
It also looks like this: When a parent pushes back on advice that contradicts what they read online, an evidence-based practitioner does not dismiss the concern — they engage with it. They explain where the information they are offering comes from and why it is reliable. They model scientific literacy and intellectual humility simultaneously.
Fictional Educational Example Not a real client
Hannah's baby is ten days old. She tells Omar, a lactation specialist, that an online parenting group told her to wait four hours between feeds so the baby gets “properly hungry.”
Omar: “Thanks for telling me what you read. Can you share what the group said about why?”
Hannah: “They said it helps the baby take bigger feeds.”
Omar: “I understand why that sounds sensible. What the research and professional guidance show is that frequent feeding in the early days is normal, and it helps build milk supply. If you're ever unsure that the baby is feeding well, your pediatric provider is the right person to check. Would it help if I showed you the hunger cues to watch for?”
Why this works: Omar does not dismiss Hannah or the group. He asks questions, explains where his information comes from, keeps the tone warm, and points to the provider for any health concern. That is evidence-based practice in a real conversation.
Every family's feeding journey is unique. The role of a lactation specialist is to provide the knowledge and support that makes that journey possible.
Who Takes This Course — and Who Is It Right For?
The DNT Network Lactation Specialist Certification is designed to be accessible to learners of all ages, educational backgrounds, and experience levels. You do not need to be a nurse, a midwife, or a physician to enroll, complete, and succeed in this course. What you do need is motivation, a willingness to engage seriously with the material, and a genuine interest in supporting families.
Students who commonly enroll in this course include:
- Birth and postpartum doulas who want to add lactation support to their professional offerings
- Newborn care specialists and night nurses who work closely with families in the early weeks
- Peer counselors and community health workers who support families in community-based or public health settings
- Registered nurses and licensed practical nurses who want deeper lactation knowledge to serve patients more effectively
- Physicians and advanced practice providers who want evidence-based lactation training to integrate into their clinical practice
- Midwives and nurse-midwives who provide comprehensive maternal and newborn care
- Dietitians and nutritionists working with maternal and infant populations
- Social workers and mental health counselors who support perinatal families and want better tools for addressing feeding-related challenges
- Early childhood educators and home visiting professionals who work with young families
- Anyone pursuing the IBCLC pathway who wants structured, aligned lactation education as part of their preparation
If you are entering this field with a professional license or advanced degree, this course will deepen and formalize your lactation knowledge. If you are entering without a clinical background, this course will give you a rigorous, scaffolded education that prepares you to serve families responsibly and confidently within a clearly defined scope.
Three Learners, Three Reasons
- Lena, a birth doula, wants to answer feeding questions confidently during postpartum visits and know exactly when to refer.
- Carlos, a nurse, wants a deeper, more current foundation in lactation and is curious about the IBCLC someday.
- Aisha, a peer counselor, wants a recognized credential to go with her lived experience and her community connections.
These are fictional examples, but you may see yourself in one of them. Different starting points lead to the same goal: supporting families well, within a clear scope.
Learners come from many backgrounds, and so do the families they serve.
What Completing This Course Will Prepare You to Do
By the time you complete the DNT Network Lactation Specialist Certification, you will have built a knowledge base and professional skill set that prepares you to:
- Provide evidence-based lactation education and support to pregnant individuals, new parents, and families during the full course of lactation
- Observe feeding sessions and guide parents through latch, positioning, and transfer concerns with confidence and skill
- Recognize and address common breastfeeding challenges using research-informed approaches
- Identify when a concern requires clinical follow-up and communicate effectively with other members of a family's care team
- Discuss the WHO Code and its implications with families and colleagues in an accurate and professional manner
- Practice culturally responsive, person-centered communication that honors the values, goals, and circumstances of every family you support
- Apply evidence-based practice principles to your work, distinguishing between well-supported guidance and opinion or anecdote
- Use appropriate professional language and documentation in your practice
- Work ethically and transparently within your scope of practice, building collaborative relationships with clinical colleagues and other providers
- Present yourself and your credential — the Certified Lactation Specialist (CLS) — with confidence to families, employers, insurance programs, and clinical partners
Many of these skills are hands-on. Hand expression, for example, is a simple way to remove milk by hand without a pump. Parents use it in many situations, and you will learn it in detail later in the course. The short video below gives you a first look at what the skill involves, so the idea is familiar when you reach it.

By the end of the course, you will feel confident observing and supporting a feeding.
Looking Ahead
The pages ahead are dense with knowledge — lactation physiology, infant anatomy, feeding assessment, milk supply dynamics, communication frameworks, professional ethics, and more. It can feel like a lot. And it is. That is because the families who will come to you for help deserve a provider who knows the material deeply, not superficially.
But here is what the research also tells us: trained support providers who approach their work with both knowledge and genuine care — who can hold the science and the human relationship together — make a meaningful, measurable difference in the lives of the families they serve. You are building that capacity right now.
Take your time with the material. Return to sections that feel unclear. Use the discussion opportunities available to you, and do not hesitate to reach out to teacher support when you need it. Evidence-based practice begins with the willingness to keep learning — and that is exactly what you are doing by being here.
Before You Move On
As you finish this lesson, take a few minutes to reflect on the following questions. You do not need to submit written answers, but thinking them through carefully will help you get more from everything that follows.
- Why are you pursuing this certification? What populations or settings do you hope to serve?
- What do you already know about breastfeeding or lactation support — and where do you feel most uncertain?
- How would you describe the scope of a lactation specialist's role to a new parent or a clinical colleague?
- If you are interested in eventually pursuing the IBCLC, what steps would you need to take beyond this certification?
Lactation support often starts during pregnancy and carries through the whole feeding journey.
