Why do kids raised in the same home react so differently to the exact same situation? In this episode, I'm joined by Alyssa Campbell, author, educator, and founder of Seed & Sew, to unpack what's really happening beneath our kids' behaviors—and why understanding their nervous systems changes everything about how we parent.

Alyssa returns to the show to talk about her new book Big Kids, Bigger Feelings, and we go deep into the overlooked developmental stage of kids ages 5–12. We discuss why "shouldn't they know better?" is the wrong question, how regulation and access to skills are two different things, and why each child's unique sensory profile determines how they experience stress, connection, discipline, and learning. This conversation will give you clarity, compassion, and practical tools to parent each child for who they actually are—not who you expect them to be.

Five Key Takeaways:

1. Every child has a unique nervous system, which determines how they experience stress, connection, and learning.
2. Knowing what to do and being able to do it in the moment are not the same thing, especially when kids are dysregulated.
3. Behavior improves when regulation improves, not when punishment increases.
4. One-size-fits-all parenting often backfires because kids need different inputs to calm and connect.
5. Understanding nervous systems builds empathy, patience, and more effective parenting strategies.
