My dd (5 months) has been sleeping through from about 3 months, but we used to have trouble settling her much before 9:30 p.m. Finally, last week, she started going to bed at 8 BUT after two blissful nights of 8 til 7:30 has now started regularly waking at 5 a.m. She isn't crying, just wide awake and gabbling to herself - she's still sharing a room with us so just ignoring her isn't really an option. When I do give in and get her up she's desperate for a bottle but will only take half. Once she's up, that's it for the day, she won't go back to bed.
Has anyone else experienced this and what did you do to deal with it? Or is it just a phase which we need to ride out?
