With phones, tablets and other devices, it may seem impossible to pull your kids away from their screens. But it’s important to set limits for them, especially during the school year. Although keeping your kids' screen time to two hours or less a day may seem challenging, Dr. Robinson said consistency is key. She stressed it’s best to have set rules in place before kids get on their devices to avoid unexpectedly stopping them in the middle of a TV show or video game. And if you’ve been more relaxed with screen time over the summer, it’s a good idea to have a conversation about it towards the beginning of the school year. You don’t want kids falling behind on homework because they’re too distracted.
