Breast Milk & the Infant Microbiome
Learn from 7 of the world’s top lactation scientists why breast milk can impact a child’s long-term health, and how to support every family, whatever their feeding journey.
The complex science of human milk made simple: HMOs, microbes and other bioactives, infant immune training, gut sealing and brain development. Covers all types of infant feeding.

New for 2026, for IBCLCs: this course may be accepted as 17 L-CERPs by IBLCE. Under the IBLCE Individual CERPs Guide for Recertification (Section IIIA), education awarded credit by another board or organisation may be counted as CERPs, for courses purchased on or after 1 January 2026.
Breast milk is so much more than food.
Human milk is a living, dynamic fluid that feeds the beneficial microbes a baby acquires at birth, trains the infant immune system, seals the infant gut and supports brain development. Understanding the science helps you explain, with confidence, why every drop matters.
- The connection between human milk and the infant microbiome
- HMOs and infant immunity

The complex science of human milk, made simple
Expand your knowledge base, from the evolution of mammalian milk to every type of infant feeding.

Session 1: Introduction to human milk
What is in human milk: its nutritive and non-nutritive components.
Session 2: Microbes in human milk
The uniqueness of breast milk microbes, where they come from, and the impact of antibiotics.
Session 3: HMOs in human milk
What human milk oligosaccharides are, their chemistry and the types found in breast milk.
Session 4: Variations of HMOs in different mothers
Why HMOs differ between mothers, including secretors and non-secretors.
Session 5: HMOs and microbes in the infant gut
How HMOs feed the beneficial microbes a baby acquires at birth.
Session 6: Infant immune training
How breast milk and the infant gut microbiome train the developing immune system.
Session 7: How HMOs affect infant body systems
The effects of HMOs across the infant’s body, including gut sealing and brain development.
Session 8: Expressed milk and donor milk
Milk banking and sharing, and the protective power of breast milk.
Session 9: HMOs and infant formula
What formula can and can’t replicate, to support every family without guilt or judgement.
For everyone who supports families with infant feeding
After an emergency caesarean, Toni Harman struggled to breastfeed her daughter and ended up topping up with infant formula. Making the documentary Microbirth showed her just how remarkable human milk is, and she created this course so that every professional supporting families can understand the science.

“Wow, what a fantastic course!”
“I learned so much about the infant microbiome and the impact of HMOs on the infant’s overall health from Microbiome Courses. The course presented the material in a clear and engaging way. The videos were very professionally done. I have already recommended the course to several colleagues!”
Kristina Chamberlain, CNM, ARNP, IBCLCClinical Director and Lead Faculty, UC San Diego Extension Lactation Program“Wow. I learned so many more amazing things about breastmilk. The best thing about the course is that it is easy to follow, and has so many experts featured. There is just enough reiteration of previous modules to reinforce the learning.”

Which IBLCE content areas does it cover?
Development and nutrition (infant): food intolerances and allergies, infant anatomy and oral challenges, complementary foods, milk banking, normal infant behaviours, and term development and growth. Maternal: composition of human milk and maternal anatomical challenges.
Does the course cover formula feeding?
Yes. The course covers all types of infant feeding, including breastfeeding, expressed milk, donor milk, peer-to-peer milk sharing and infant formula.
Is it live or self-paced?
Self-paced. You can start as soon as you enrol and learn online in your own time.

I’m new to the microbiome. Where should I start?
This course stands on its own, but if you’d like a broader introduction first, our Microbiome Foundation Course (5 hours CPD / CE) covers the microbiome from pregnancy through birth and breastfeeding.
