I know this is very subjective, but i am interested in how others do it. Our ds gets a bit obsessive about computer games. He is allowed on computer/wii on wednesday evening, saturday and sunday (not all day, but usually few hours). Sometimes he gets to go on friday eve too. I do worry this is too much. He even acts out the games with his lego/ sisters/ friends when he is not allowed to play them. However, he generally behaves ok, and is doing well at school.
