How do you deal with a 3-4yo who refuses to sleep early? (9pm) and sleeps only closer to 11pm? I'm thinking of making my LO exercise until she KO. Heh.

Dim lights in the hour before bedtime, as well as slow, calm routines, help kids' bodies know that it's time to sleep. If you can take him up to his bath at 6:00, be in bed at 6:30 for stories, and turn the lights out at 7:00pm, he's much more likely to fall asleep than if you put him into pajamas at 7:25 and snap the lights off. The key is to watch for those yawns that signal he's getting sleepy. If he kicks into "overdrive" mode, his body will be pumping out adrenaline, and getting him into bed will be much harder.
