My dd is 9 and she gets ready for bed at 8:30, and is in bed by 9:00pm.
She probably doesn't go to sleep until 9:30-9:45. That seems to be okay for us. I get her up at 7am, but most of the time she wakes up on her own either at that time or earlier.
Sleep experts say that if kids wake up on their own in the morning, this means that they're getting enough sleep. If you have to drag them out of bed, they aren't getting enough.
