You could fill an entire bookshelf with guides on babies and toddlers, or the best strategies for dealing with teenagers. But for Dr. Kenneth Ginsburg, one of the most critical stages for child development is the pre-adolescent phase, when kids really begin to push their parents away and first ask the biggest questions of their lives: Who am I? Am I normal? Where do I fit in?

On this episode of Paternal, Dr. Ginsburg returns to the show for the first in a series of special episodes devoted to the issues affecting our kids. He dives deep into the idea of brain puberty and what's happening in the minds of kids in this pre-adolescent phase, why they're trying harder than ever to break free from their parents, how screen habits figure into their development, and why you should leave your own painful memories of middle school out of the conversation with your kids.

Dr. Kenneth Ginsburg is a pediatrician specializing in Adolescent Medicine at the Children's Hospital of Philadelphia and a Professor of Pediatrics at the University of Pennsylvania School of Medicine. He is also the author of Lighthouse Parenting: Raising Your Child With Loving Guidance for a Lifelong Bond.
