Don't set rigid time limits.
If a child is engaged in high-quality content that is helping him to use his imagination or learn a new skill, having a set amount of time with a screen, in Ingrid's opinion, can actually be detrimental. "Time limits will vary depending on your situation," she said. "You could put a hard and fast time limit on things, but there are some interactive activities that kids will do that take time. They might be right on the edge of their next big thing, and to have a hard cutoff at 30 minutes, I think that they can lose a lot of creative opportunity in those cases."
