limiting TV & computer game time in Parenting and advocacy has some ideas.

This is what I do. On a school day 1/2 hr computer time allowed and 1 hr on weekend. I keep it a little loose. If they are playing something good for them and it's a rainy day they can do more.

We had some problems with games getting too intense and behavior issues related to computer. Last summer, I took away all my son's game time on the computer and got him a online writing course which he loved. After the summer, he got games back except for one and he's not messing with me anymore on this.
