The Infant Microbiome: Cheryl Sew Hoy on Baby Gut Health, Colic, Eczema, Allergies, Sleep & the First 1,000 Days

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.   Learn more about Tiny Health on Instagram @tiny.health and check out the Tiny Health blog   Resources: • Which lab test is best for you? → • Get functional lab testing → • Follow along on Instagram →   In this episode: 01:05 – Introducing Cheryl Sew Hoy, founder of Tiny Health 03:58 – The story behind Tiny Health 11:27 – Baby gut-related symptoms 15:35 – Why the first 1000 days matter so much 17:59 – Conventional medicine vs. microbiome testing 25:09 – Case study: Noah's gut test results after a C-section birth 28:18 – Natural ways to support infant gut health 32:29 – Why both parents' gut health matters too 38:42 – Missing beneficial bacteria vs. pathogens 43:58 – Building gut resilience in children 50:29 – Introducing solids, allergens, and microbial diversity 55:42 – Key takeaway for parents   I'm so grateful to have you here, friend.
