Do other kids go to sleep?

Mine won't. I just don't get it. Avery is actually laying in bed, in the dark, talking to himself. This can go on for hours. If he just stopped talking he would go to sleep. Zachery just does not sleep. He's playing on the computer now. I'd say he's good for at least another hour and a half. I have never in my life known a child who needed less sleep.

Last night I couldn't take it any more, no wait that was Monday night. I was the first one asleep. Last night Zachery decided he wanted to sleep with Avery. But instead of laying there he tormented Avery for hours, keeping everyone away. Then he decided Avery needed to sleep in my bed, that we all three should sleep there. So I'm in bed and the kids leave. They come back out to the living room. I understand why Avery did it. He was trying to get away from Zachery so he could sleep. But it didn't work, Zachery followed him. I just don't know how to get him to settle down. It doesn't matter if the routine is the same, it doesn't matter if you change it. The child does not go to sleep until he is ready. I think I need more sleep than he does. lol
