For kids over the age of 6, the American Academy of Pediatrics says no more than 60 minutes on school days and 2 hours on non-school days. Kids under 6 should spend closer to 30 minutes. It's also appropriate for parents to know and approve the games their kids are playing. Avoid any games with graphic violence or sex.

For kids and teens 5 to 18 years old, experts recommend that parents think about how much their child uses any media. This includes playing video games on gaming consoles, tablets, or smartphones. Using media should not take the place of getting enough sleep or being physically active.
