It’s Their World
Teens, Screens, and the Science of Adolescence
“I wrote this book to remind you that as your teen moves through online and offline spaces they are engaging in the biggest and most important developmental task of them all: growing up. Having a caring adult in their corner, and not just a device in their hand, makes all the difference in the world.”
“Parents who want to choose connection over conflict will find pages and pages of ideas to try today.”
—Dr. Emily Weinstein, researcher and co-founder, Center for Digital Thriving at the Harvard Graduate School of Education; and coauthor of Behind Their Screens: What Teens Are Facing (And Adults Are Missing)

Adolescence is a window of opportunity. Let’s not miss it.
It’s Their World tackles crucial topics like cyberbullying, sexting, and body image—but it’s not structured around digital risks. Why? Because chasing headlines or the latest trends only fuels feelings of overwhelm and worry-whack-a-mole.
Instead, this book dives into the core developmental tasks of adolescence, guiding you through the big questions every teen must navigate:
“What am I capable of?”
“Who am I?”
“Where do I belong?”
“How can I contribute?”
With insights from the latest research, you’ll discover how technology can empower your teen—or hinder their growth—as they work to answer these essential questions.
You want to do more than just protect your teenager from harm. You want to prepare them to live a whole, connected, and meaningful life. As you will learn in this book, the adolescent years are a time of profound growth and opportunity to shape these kinds of positive futures.
