#332 | The Hidden Power of the Infant Microbiome: Optimizing Exposure in Birth & Breastfeeding

In this episode, filmmaker and microbiome advocate Toni Harman joins us to explore the groundbreaking science behind establishing the infant microbiome—and why the earliest moments of life matter so much for lifelong health. Toni shares her personal journey from an unexpected C-section to uncovering how birth methods, antibiotics, and feeding choices shape immunity, metabolism, and risk of chronic disease over our lifetime.Key Points Discussed Include:Why vaginal birth, skin-to-skin contact, and early exclusive breastfeeding are the gold standard for seeding a healthy microbiome;How C-section birth changes microbial exposure—introducing hospital and staff microbes instead of the mother’s;Why even a single bottle of formula can shift the gut microbiome, and how exclusive breastfeeding and skin-to-skin can help restore balance;The fascinating recent research about vaginal seeding during C-sections...is it actually effective?The impact of newborn exposure to maternal gut microbes at birth;How the microbiome begins to “lock in” by age 2–3, and ways to keep building resilience through early childhood.Buckle up for some mind-blowing ideas in this episode! As always, Mother Nature has the perfect, albeit a little dirty, plan! Microbirth FilmInstagram: Toni HarmanWatch this episode in full video format on YouTube.**********Our sponsors, Patreon, and contact info below:Send us Fan Mail Support the showAccess our workshops: Have a Physiologic Birth in the Hospital and Ultrasound: The Research vs RhetoricNeeded <-- for 20% off DrinkLMNT <--  for FREE 8-day supplyPrimally Pure Skincare: Use code DOWNTOBIRTH Postpartum Soothe: Use code DOWNTOBIRTHENERGYBits Superfood<--for 20% offJoin Patreon hereIG @downtobirthshowCall 802-GET-DOWN.
