My DD has got her first two teeth this week, but I have noticed that her sleep routine is out of whack. She has slept through the night since two months with the occasional bottle needed half way through the night. But the last week she refuses to go to bed at a reasonable hour (usual bed time is approx 7.30pm but last night she didn't go down until after 10pm) or if she does go down early, she is wide awake between 1am and 3am. And because of this unusual routine, if she goes to bed late or has a bottle during the night, she is sleeping until after 9.30am, which means we can't really start the day until late, but then she has a nap, so is having lunch later and.... why?

Right now, she is laying in her cot 'yayyayaya'ing away to herself. It's 9pm and she hasn't had more than 30mins sleep since 2.30pm. She should be flaked out by now.
