I've read to limit TV and Screen time all together to a maxium of 2hrs.a day, not 2 hours each.

It's ok for a child to just sit still and be quiet sometimes, even if he is a little bored. That good coping skills. I would suggest lots of books around and have a bedtime routinue of reading. My children 8 & 11 both read every night before bed. Infact they get mad if they get home late and don't have reading time.
