Two questions that work at every age
Davis packs the research into two questions a parent can ask about any app, show or game. Is it self-directed: did the child choose to start it, and can they stop it when they want? Is it community-supported: are there people around, or inside the experience, who help the child make sense of it? "The process of development is going well," she writes, "when children experience a sense of initiative and ownership over their actions, a feeling that they can succeed and grow, and a sense of belonging and connection."

What a toddler needs from a screen differs from what a teen needs
The book moves through the ages in order. For toddlers and preschoolers, the key skill is executive function, and the best tech lets the child set the pace instead of grabbing their attention with constant pings and rewards. Later the focus moves to learning, play and friendship; her example of tech that is both self-directed and community-supported is friends designing a game together in Scratch. For tweens and teens, the questions are identity and belonging, and she notes that strict rules can read to a teenager as distrust or hypocrisy, which drives a wedge between parent and child.
Every chapter ends with homework for parents and for app designers
"Taking Stock of the Three Ds" closes each chapter. It restates what is going on developmentally, gives parents questions to ask about their own kid, and tells designers what to build. Seattle's Child called these 2- to 3-page sections the most useful part of the book.
Hear her explain it
Davis talks through the book with the Artificiality Institute, including how kids treat AI as if it were human:
And with Debbie Reber on Full-Tilt Parenting, including why families with neurodivergent kids often feel more tension around screens:
Dense in places, since it was written by a researcher
The research reads heavy at times, and the book is closer to a well-organized review of the field than a quick parenting guide. Davis brings in her own experiences as a parent, which helps. If you are short on time, read the chapter for your kid's current age and its Three Ds section.

Devorah Heitner, author of Screenwise, called it "the book we've been waiting for." For a practical plan that rests on the same idea of kids choosing what fills their time, see Michaeleen Doucleff's Dopamine Kids. For the family side of the research, Sonia Livingstone and Alicia Blum-Ross's Parenting for a Digital Future is the natural companion.
