It varies.
Ds2 is 2.10. If he has a nap in the day, he gets to see daddy and play until about 8. He doesn't always go to sleep then, but is in bed.
On Monday, his first day at nursery, he didn't have a nap and was a nightmare, so went to bed- and fell promptly asleep- at 6 o'clock.
He usually wakes between 6.30 and 7 and gets up about half an hour after that.
