Description: Most parents have heard that breastfeeding is beneficial. What far fewer understand is why those first feedings matter so much, what colostrum does beyond nutrition, and how early feeding choices shape the gut microbiome, immune system, and long-term health.Today, we’re joined by Dr. Rhonda Trust, PhD, registered dietitian, professor of health communication, and longtime breastfeeding educator, for a conversation about newborn gut health, colostrum, skin-to-skin contact, formula supplementation, and the larger systems influencing infant feeding decisions.We talk about what happens when babies receive formula in the hospital before breastfeeding is established, why nutrition education is still surprisingly limited in conventional medical training, and how formula marketing continues to shape the messaging parents receive.We also get into donor milk, birth mode, bacterial transfer, and why the newborn microbiome is about far more than digestion.We discuss:• What colostrum actually does in the newborn gut • Why the first feeding matters differently from feeding decisions made later • How skin-to-skin contact helps establish a healthy microbiome • Why formula is so often introduced before breastfeeding is fully supported • The connection between gut health, immune development, and chronic illness • Why many pediatricians receive limited breastfeeding and nutrition education • The role of donor milk when breastfeeding isn’t immediately possible • How modern infant feeding culture became so disconnected from biologyIf you’ve ever been told “a little formula won’t hurt,” or wondered why the first few days matter so much, this episode provides much food for thought.**********Send us Fan Mail Access our workshops: Have a Physiologic Birth in the Hospital and Ultrasound: The Research vs RhetoricNeeded DrinkLMNT Primally Pure Skincare: Use code DOWNTOBIRTH Postpartum Soothe: Use code DOWNTOBIRTHENERGYBits SuperfoodJoin Patreon hereIG @downtobirthshowCall 802-GET-DOWN.
