When do your kids go to bed?

Also, I need suggestions on my 9 yr. old’s sleep problems, he always takes about 1½ hour to get to sleep.

My 9 year old:
Summer: Bed at 12:45 A, Asleep at 2 A, Up at 11 A
Weekends: Bed at 11:00 P, Asleep at 12:30 A, Up at 10 A
School nights: Bed at 9:00 P, Asleep at 10:45 P, Up at 6:30 A

My 5 year old:

Weekends: Bed at 9:45 P, Asleep at 10:00 P, Up at 9:00 A
