Focus more on maximizing in-person activity and sleep than on total screen hours. The main harm done by most screen activities is the opportunity cost, which directly drives two of the four foundational harms that I described in chapter 5: social deprivation and sleep deprivation. If your children are spending a lot of time in person with friends, such as on sports teams or in unstructured play or hangouts, if they are getting plenty of sleep, and if they show no signs of addiction or problematic use on any devices, then you may be able to loosen up on the screen-time limit.
