My daughter just turned two. My husband is complaining that she plays iPad too much, and it's bad for her eyes. On one hand, I agree. But on the other hand, I feel iPad is necessary. It has lots of educational app and game. My daughter learned a lot from it. And while she's playing with iPad, I can do some house work. (Sometimes I feel dad is just a dead person at home, doesn't help at all). Maybe I just set a hard limit on how much time she can play on iPad daily. Any suggestion?
