DD goes to bed at 8.30, always! She has chosen that time herself and it's too hard to get her to sleep before then, and anytime after she's really over tired. Then she wakes between 5 and 6am. If I'm lucky 6.30am. So only around 9hrs sleep here. Was better in winter when it wasn't so light in the mornings. She has a 2hr day nap as well.
