Sleeping Beauty!

By day cheeky is a total jekyl and hyde, he can go from dancing and signing, to screaming blue murder in about 20 seconds. Sometimes i can't help but laugh in total shock, its is just ridiculous. By night he is pretty steady, generally goes to bed at 7 oclock, bottle, bath (sometimes the opposite way around) story, bed. Sometimes late nights are unavoidable, and an early night is often the only way to keep us both sane. I have however noticed something which seems a little strange. Earlier in the week cheeky had a late ish night, it was about 8.30pm when he went to bed, i was thinking he would probably sleep in a little later, how wrong i was he woke at 5.10am (his normal waking time being about 6.30). Last night he had an early night, he just decided after teatime he just didn't want to be awake any longer and cried for night nights, so he was asleep by about 5.50pm (really early i know) yet this morning he didn't wake until 7.30am?! One very baffled mummy here?!!
