The optometrist told my kids, no more than 2 hours of screen time a day. So that's what they get. They have to decide how to spend it. T.V. shows, computer time, or video games. I made a chart that broke it down into 10 minute increments. I also allowed them to turn unused time into tokens that can redeem treats. That last part was more important when they were younger. But my 10 year old is currently only using 1 hour a day so she can turn all her extra time into a new science kit.
