The Developing Brain: A Pediatrician’s Guide to Understanding Child Behaviour

Why do children misbehave—and what is their behaviour really trying to tell us?

In this episode of the Where Parents Talk podcast, host Lianne Castelino speaks with paediatrician, author, and mother Dr. Kristen Cook about the science behind children’s behaviour and what today’s overwhelmed parents need to know.

Drawing on more than 15 years of clinical experience, Dr. Cook explains how understanding brain development—from toddlers to teens—can transform the way parents respond to tantrums, lying, emotional outbursts, and risk-taking behaviour.

Parents will learn why the brain doesn’t fully develop until the mid-20s, how emotional intelligence is reshaping modern parenting, and why misbehaviour is often a signal of an overwhelmed brain—not defiance.

This episode explores practical strategies for raising resilient, emotionally healthy kids while reducing parenting guilt and stress.

In this episode, parents will learn:

1. Why children’s brains aren’t wired for adult logic
2. The difference between discipline vs punishment in effective parenting
3. How brain science explains teen risk-taking behaviour
4. Why parenting each child’s temperament matters—especially with siblings
5. The importance of emotional regulation and modeling calm behavior
6. Practical tools like the “Duck on a Pond” technique to manage parenting stress

This podcast is for parents, guardians, teachers and caregivers to learn proven strategies and trusted tips on raising kids, teens and young adults based on science, evidenced and lived experience.

You’ll learn the latest on topics like managing bullying, consent, fostering healthy relationships, and the interconnectedness of mental, emotional and physical health.
