Your Baby’s Gut Is Talking to Their Brain: The Surprising Connection Between Gut Health & Emotional Development with Dr. Stephanie Culler Ep. 148

What if your baby’s gut health could influence more than digestion?

In this fascinating episode of the Masterful Parenting Podcast, I’m joined by Stephanie Culler, Ph.D., scientist, entrepreneur, mother, and Co-Founder & CEO of Persephone Biosciences, to explore the powerful connection between the infant gut microbiome, brain development, emotions, behavior, and lifelong health.

Stephanie is the lead author of the My Baby Biome study, the largest U.S. study to profile the infant gut microbiome, and her scientific work spans everything from infant health to oncology.

Together, we dive into why the first 1,000 days of life are such a critical window for development and how early experiences—including birth, feeding, antibiotics, and nurturing relationships—can influence a child's developing microbiome and overall wellbeing.

Stephanie also shares her personal journey from cancer research to becoming a scientist, entrepreneur, and mother—and how motherhood changed the way she thought about prevention and lifelong health.

Most importantly, we talk about what parents can actually DO.

No fear. No perfectionism. No adding another impossible list of things to worry about.

Just simple, evidence-based ways parents can support their baby's gut health and create a strong foundation for lifelong wellbeing.
