My 15 year old DS is constantly on his computer and/or ipad, from the time he gets home from school until going to bed. He does stop every now and then to do homework/revision etc so I'm not worried about that aspect. At the moment I have parental controls set to turn the internet off at 11pm weeknights and 12 Fri/sat nights. He's not happy with this as until recently had no restriction on time, as I naively thought he was going to sleep when the lights were out. Yesterday we had a big argument with him wanting a 1am curfew weeknights and unrestricted at other times. The compromise I made was midnight and 2am but neither of us are happy with this and he wants to continue negotiating today, saying none of his friends have any time limit.
