M.T.
A., I would not have t.v. or video games in their rooms. Also, if you are sending them all to bed at the same time, I'd put an end to that too. An 11 year old doesn't need to go to bed when a 3 or 6 year old does. If you spread out the bedtimes so that each child gets an appropriate amount of sleep for his age and the older ones have the privilege of a later bedtime that I believe in, less of a problem. NO play, no wrestling. Put the 3 y.o to bed, at say 8:00. The 6 can go to bed once the 3 is asleep, so around 8:30-8:45, which is plenty late enough and there shouldn't still be kids his age playing outside. If the 11 y.o. is going to bed at 8:30 right now, that's just too early for a middle schooler especially over the summer. He shouldn't be going to bed when a 3 year old does. Send him in around 9:00-9:30. Good luck
