Whether you’re at a restaurant or on an airplane, you can’t miss changes in adult-child interactions from just a generation ago. Everyone is plugged in. It seems almost quaint to see kids and adults engaged together in screen-free play. Four-year-olds now consume three hours of media per day, and fourth graders more than five hours. And it is not just youth—adults are also increasingly finding it difficult to turn off their digital lives. This has inspired a tremendous amount of philosophizing about how smartphones, iPads, and gaming consoles may be hurting both childhood and parenting.
