The other problem with setting strict time limits on screen time is that it sets up a forbidden fruit paradox. Kids think it's something special, so if you give then two hours of screen time every day, they are going to use the full two hours.
David Lord, CEO of JumpStart Games, which makes learning-based games for kids, suggests turning the logic around.
"We are not going to win the battle for limiting their time on their tablets and smartphones, because they’ll use their devices every chance they get," he said. "Given this, rather than trying to limit this technology usage, it’s important for parents to focus on carving out big chunks of time for 'unplugged family time' or outdoor play."
Lord said. "As parents, it’s our responsibility to commit to these bigger activities, where families can interact and teens can learn to detach from their devices, as opposed to trying to take away the devices altogether."
