If it's working then fine. My dd is 7 and requires a lot of sleep so she goes to bed at 8. This is a recent thing too. 6 months ago she was going to bed at 7. The recommended amount of sleep for a 7 yr old is 10-11 hours. My dd goes to bed at 8 (asleep by 8:30) and up at 6:40 am. She fools around so much in the morning she has to get up 1 1/2 hours before her bus picks her up.
