mainly dd2 (3.5), sleeping time has crept later and later. She likes someone to stay, but just messes about. So tonight she asked for a book, I gave it to her and told her that she could look at it, but I wouldn't stay. It is now 10pm, and she had got into bed with her big sister (exhausted from 2 nights away with her cousin). But she is still awake. Not helped by an hour and a half nap in the car on the way home, of course, but this is a more regular version of what happens. She gets up at 7 (we always wake her), I suppose 11 hours probably is enough sleep for a 3.5 year old?
