What Is a Lactation Consultant? The Complete Guide to Lactation Nursing, IBCLC Certification and Salary

Illustrated header for a guide to what a lactation consultant is, with stickers of a baby bottle, a milk drop, a breast pump and a stethoscope

A lactation consultant is a health care professional who specializes in breastfeeding and chestfeeding, helping parents and babies with latch, positioning, milk supply, pumping and feeding problems. A lactation nurse is a registered nurse who has added this specialized training, often earning the IBCLC credential, the gold standard in lactation care. Lactation consultants work in hospitals, NICUs, pediatric offices, public health programs and private practice, supporting families from the first feeding through weaning.

This guide covers what lactation consultants and lactation nurses do, IBCLC vs CLC vs other credentials, a good latch, breastfeeding positions, signs a baby is getting enough milk, common challenges like cluster feeding, engorgement and mastitis, pumping and paced bottle feeding, how to become a lactation consultant, salary and World Breastfeeding Week.

What is a lactation consultant?

A lactation consultant is an expert in human milk feeding. Lactation consultants help families with the clinical side of feeding: assessing latch and milk transfer, troubleshooting pain, managing low or high milk supply, supporting babies with tongue-tie or prematurity, creating pumping plans and helping parents meet their own feeding goals.

The term is used broadly, but the most widely recognized professional credential is the IBCLC (International Board Certified Lactation Consultant). Lactation consultants support every family's choices, whether that means exclusive breastfeeding, pumping, combination feeding or transitioning to formula.

What is a lactation nurse?

A lactation nurse (or nurse lactation consultant) is a registered nurse who specializes in breastfeeding support. Many work on postpartum units, in the NICU or in labor and delivery, and many hold the IBCLC. Not every IBCLC is a nurse: dietitians, physicians, speech therapists and trained non-clinical professionals can also become IBCLCs. RN lactation consultants bring added clinical training, such as assessing the parent's and baby's overall health, giving medications in the hospital and managing complex medical cases.

What does a lactation consultant do?

  • Feeding assessments: watching a full feeding to check latch, positioning, sucking and swallowing
  • Weighted feeds: weighing the baby before and after a feeding to measure how much milk was transferred
  • Pain and nipple trauma: finding the cause of pain and helping fix the latch
  • Milk supply support: creating plans for low supply, oversupply or a delayed milk "coming in"
  • Pumping plans: teaching pumping, flange fit, hand expression and milk storage, especially for NICU parents and parents returning to work
  • Special situations: supporting premature babies, twins, babies with tongue-tie or cleft palate, adoptive parents and parents with medical conditions
  • Feeding tools: teaching the use of nipple shields, supplemental nursing systems, syringes, cups and paced bottle feeding when needed
  • Education: prenatal breastfeeding classes and teaching hospital staff
  • Emotional support: helping parents who feel overwhelmed, frustrated or worried, and respecting their goals
  • Referrals: coordinating with pediatricians, OBs, midwives and specialists when needed

IBCLC vs CLC vs other lactation credentials

Credential Offered by Training Scope
IBCLC (International Board Certified Lactation Consultant) International Board of Lactation Consultant Examiners (IBLCE) Health science courses, lactation-specific education, hundreds to 1,000 clinical hours and a board exam The highest lactation credential; handles complex clinical cases
CLC (Certified Lactation Counselor) Academy of Lactation Policy and Practice (ALPP) A short training course and exam Breastfeeding counseling and support for common concerns
CBS, CLE and similar Various organizations Shorter courses Basic breastfeeding education and peer support
Peer counselors Programs like WIC and La Leche League Program-specific training Mother-to-mother support and encouragement

All of these roles help families, and many lactation professionals start with a counselor credential and later work toward the IBCLC.

What a good latch looks like

A deep latch is one of the most important parts of comfortable, effective breastfeeding. Signs of a good latch include:

  • The baby's mouth is open wide, with lips flanged outward
  • The baby takes in a large mouthful of breast, not just the nipple, with more of the areola visible above the top lip than below the bottom lip
  • The baby's chin touches the breast and the nose is clear
  • Sucking becomes slow and rhythmic, with audible swallowing
  • After the first few seconds, feeding feels like a tug, not pinching or ongoing pain
  • The nipple looks rounded, not flattened or creased, after the feeding

Pain that lasts through the feeding, cracked or bleeding nipples or a baby who seems hungry right after feeding are all reasons to reach out to a lactation consultant.

Breastfeeding positions

Position How it works Often helpful for
Cradle hold Baby lies across the lap, head in the crook of the arm on the same side as the breast Older babies with an established latch
Cross-cradle hold Like the cradle, but the opposite hand supports the baby's head and neck Newborns and learning to latch, because it gives more control
Football (clutch) hold Baby is tucked along the side, under the arm, with the parent supporting the head After a C-section, larger breasts, twins and premature babies
Side-lying Parent and baby lie on their sides, facing each other Resting during feeds and recovery after birth
Laid-back (biological nurturing) Parent reclines, and the baby lies tummy-down on the parent's chest Encouraging the baby's natural feeding reflexes and fast milk flow

Safe sleep reminder: if a parent might fall asleep while feeding, the safest place is a bed cleared of pillows and blankets, not a couch or armchair. The baby should always be placed on their back in their own sleep space afterward.

Signs a baby is getting enough milk

  • Feeding often: newborns usually feed about 8 to 12 times in 24 hours
  • Diapers: wet and dirty diapers increase over the first days. By around day 5 or 6, many babies have about 6 or more wet diapers and several yellow stools a day.
  • Weight: some weight loss in the first days is normal, and most babies are back to their birth weight by about 10 to 14 days
  • Swallowing during feeds, and a baby who seems content after most feedings

The first milk, colostrum, comes in small amounts but is rich in antibodies. Milk volume usually increases, or "comes in," around day 2 to 5 after birth.

This guide is educational. Always follow the advice of your baby's health care provider and contact them with any concerns about feeding, weight gain or diapers.

Common breastfeeding challenges

  • Cluster feeding: periods when a baby wants to feed very often, sometimes every hour, often in the evening or during growth spurts. It is normal and helps build milk supply.
  • Engorgement: breasts that feel very full, hard and painful, often when milk first comes in. Frequent feeding, gentle hand expression to soften the areola before latching and cold compresses after feeds may help.
  • Mastitis: inflammation of the breast that can cause a painful, red or swollen area, often with fever and flu-like symptoms. Current guidance from the Academy of Breastfeeding Medicine emphasizes continuing to feed normally, avoiding deep massage and overpumping and using cold and anti-inflammatory measures. Anyone with fever or worsening symptoms should contact their health care provider, since antibiotics may be needed.
  • Sore or damaged nipples: usually caused by a shallow latch
  • Low milk supply: often improved by more frequent, effective milk removal, with a lactation consultant's help finding the cause
  • Tongue-tie: a tight band under the tongue that can sometimes affect latch; lactation consultants assess feeding and refer to providers when needed
  • Nipple shields: thin silicone covers that can help some babies latch, best used with guidance from a lactation consultant

Pumping, hand expression and paced bottle feeding

Many parents pump to build supply, feed a premature baby or return to work. Lactation consultants help choose a breast pump, check flange size, build a pumping schedule and teach safe milk storage. Hand expression, removing milk by hand, is especially useful for collecting colostrum in the first days.

Paced bottle feeding is a way to give a bottle that mimics the slower flow of breastfeeding. The baby is held more upright, the bottle is held more horizontally, and the caregiver gives breaks during the feed. This helps prevent overfeeding and can make it easier for babies to go back and forth between breast and bottle.

Where do lactation consultants work?

  • Hospitals, on postpartum, mother-baby and labor and delivery units
  • NICUs, supporting pumping and feeding for premature and sick babies
  • Pediatric offices and outpatient lactation clinics
  • Public health programs, including WIC (see our public health nurse guide)
  • Private practice and home visits
  • Telehealth, offering virtual consultations
  • Birth centers and midwifery practices (see our nurse-midwife guide)

How to become a lactation consultant

There is more than one path. For nurses, a common route is:

  1. Become a registered nurse by earning an ADN or BSN and passing the NCLEX-RN.
  2. Work in maternal-child health, such as postpartum, labor and delivery, NICU or pediatrics.
  3. Complete lactation-specific education from an approved provider.
  4. Gain lactation clinical hours by providing breastfeeding support on the job.
  5. Apply for and pass the IBCLC exam through IBLCE.

Non-nurses can also become IBCLCs through other health professions or through accredited lactation programs and mentorships.

IBCLC certification requirements

To sit for the IBCLC exam, IBLCE requires:

  • Health science education: college-level courses in subjects like biology, anatomy and physiology, nutrition and infant development (health professionals like RNs usually already meet this)
  • Lactation-specific education: a set number of hours of lactation-focused education
  • Clinical experience, through one of three pathways:
    • Pathway 1: recognized health professionals (including RNs) or recognized breastfeeding support counselors complete about 1,000 hours of lactation-specific clinical practice
    • Pathway 2: graduates of an accredited academic lactation program complete supervised clinical hours as part of the program
    • Pathway 3: candidates complete supervised clinical hours through a mentorship with an IBCLC
  • Passing the IBCLC exam

IBCLCs recertify every five years through continuing education, with a retest required periodically. Requirements change, so check IBLCE for current details. The International Lactation Consultant Association (ILCA) is the main professional organization for IBCLCs.

How much do lactation consultants make?

The U.S. Bureau of Labor Statistics does not publish a separate salary for lactation consultants. For nurses, BLS reports that the median annual wage for registered nurses was $97,550 in May 2025, according to the BLS.

Lactation consultant pay depends on background (RN or non-RN), credential (IBCLC usually pays more than counselor credentials), setting (hospital, clinic, public health or private practice), location and experience. Private practice lactation consultants set their own rates, and many work with insurance companies, since the Affordable Care Act requires most health plans to cover breastfeeding support and equipment.

What is it like to be a lactation consultant?

  • Tender moments: lactation consultants are there for one of the most intimate and emotional parts of early parenthood.
  • Problem-solving: every parent-baby pair is different, and finding the answer can take detective work.
  • Patience: sessions often take an hour or more and need calm encouragement.
  • Emotional support: many parents feel guilt, stress or grief about feeding, and lactation consultants help them feel heard.
  • Celebrating wins: the first comfortable latch or a baby who finally gains weight is a big deal.
  • Respecting choices: great lactation consultants support each family's goals without judgment.

A short history of lactation support

  • 1956: seven mothers in Franklin Park, Illinois, found La Leche League to support breastfeeding at a time when formula feeding was the norm.
  • 1985: the first IBCLC exam is given, creating a professional credential for lactation consultants. The International Lactation Consultant Association is founded the same year.
  • 1991: WHO and UNICEF launch the Baby-Friendly Hospital Initiative, encouraging hospitals to follow the Ten Steps to Successful Breastfeeding.
  • 1992: the first World Breastfeeding Week is celebrated.
  • 2010: the Affordable Care Act requires most health plans to cover breastfeeding support and breast pumps.
  • 2022: the federal PUMP Act expands workplace protections for employees who need to pump.

When is World Breastfeeding Week?

World Breastfeeding Week is celebrated August 1 to 7 every year, and August is National Breastfeeding Month in the United States. It is the biggest time of year to celebrate lactation consultants and lactation nurses. National Nurses Week (May 6 to 12) is another great time.

Ideas for celebrating lactation consultants

  • Bring snacks and water bottles, since lactation teams spend all day reminding parents to hydrate.
  • Share thank-you notes and photos from families they helped.
  • Sponsor IBCLC exam fees, continuing education or ILCA membership.
  • Recognize the postpartum and NICU nurses who support feeding around the clock.
