The Infant Microbiome: Cheryl Sew Hoy on Baby Gut Health, Colic, Eczema, Allergies, Sleep & the First 1,000 Days
EPISODE #95 — JUN 5, 2026
What happens in your baby's gut during the first 1000 days of life can have a profound impact on their future health. In this episode, I'm joined by Cheryl Sew Hoy, founder of Tiny Health, to talk about the infant microbiome, how it develops, and why it's becoming such an important piece of the conversation around children's health. We discuss everything from C-sections and antibiotics to colic, eczema, food allergies, breastfeeding, and the critical role gut health plays in immune development. Whether you're currently raising a baby, planning for a future pregnancy, or curious about how early life influences long-term health, this conversation is full of practical insights and fascinating gut science.
