"The Crucial Years is the ultimate survival guide….

“No longer the forgotten years, The Crucial Years redefines the ages from 6-12 as a time of opportunity to educate and empower kids. With puberty beginning much earlier, Ziegler provides a developmental framework for understanding the intersection of kids' physical and emotional transformation during middle childhood. Her clear explanations and parenting scripts will be a useful tool for any parent navigating this period!”

"I wish this book were around when my kids were younger. At least I have an excuse for doing it all wrong."
Karen Alpert
author of the New York Times bestseller I Heart My Little A-Holes
"Seems like every stage of childhood is fraught with some kind of anxiety -- often on the part of the parents! Sheryl Ziegler helps us realize that discomfort does not mean disaster, and that as our 'middle childhood' kids surprise and sometimes worry us, that's not only normal, it's good. Changes ahead! Yikes! Yay!"
Lenore Skenazy
author of Free-Range Kids

An essential guide for parents and caregivers, this book offers insights, strategies, and understanding to navigate middle childhood (ages 6–12). Dr. Sheryl Ziegler, a seasoned clinical psychologist and mother, highlights ways to foster resilience, encourage open communication, and build lasting connections during this crucial period.
There is a pivotal sea change happening in children’s development. The age of puberty has been trending earlier for decades, and now starts as young as 8 years old in girls and 9 in boys. Bullying doesn’t just happen on the playground, but over text and DM. Depression and anxiety are drastically on the rise. Couple earlier puberty with ill-equipped, developing brains and the onslaught of new media and stressors that never existed when we were kids, and it’s clear that parents need a new guide to raise this new generation.
The Crucial Years is your essential handbook to navigating the often misunderstood and overlooked years of middle childhood (ages 6–12). As a mom and clinical psychologist, Dr. Sheryl Ziegler knows firsthand how challenging these years can be—yet she also recognizes that this is a tender age and pivotal opportunity to connect with your child before adolescence. Dr. Ziegler masterfully unlocks the enigma surrounding modern puberty and offers evidence-based strategies, interventions, and answers to middle childhood’s most perplexing questions and concerns. In these pages, she provides:
- Science-based advice to recognize the first signs of puberty and navigate the changes to come.
- Candid and actionable guidance for getting your kids to talk about anxiety, depression, and their complicated feelings.
- Insight into the changing world of gender and sexual identity, and how to guide your child through this complicated new landscape.
- A thoughtful and sensitive discussion of how race intersects with puberty and mental health, and how all parents can approach this mindfully and inclusively.
- A clear explanation of the invisible threads linking mood swings, self-image, and social media exposure.
- Road-tested, real-world guidance to handle bullies, mean girls, and other friendship and social challenges.
With The Crucial Years, you have all that you need to guide your child through the hazards and thrills of puberty and help them emerge as well-rounded, confident young adults.
