5 Month old sleep pattern problems after daycare

My 5 month old has had sleep problems since she started daycare 1 1/2 months ago. She seems to be napping about the same amount of time(most of the time), but wakes up around 5 am(or earlier) and isn't able to stay back asleep. I rock her back to sleep and 10 minutes later she wakes up again. She used to sleep until 8am before I started back to work. Maybe she just doesn't need as much sleep? What do you think?


I am having some problems with her daycare and need to have a discussion with the supervisors about nap rules again. They decided yesterday to reduce her nap time since I told them she hadn't slept well and might be a bit grouchy. They thought this would make her sleep better the following night. I of course did not ask them to do this. Needless to say she fell asleep as soon as she got home and we couldn't wake her. She then woke up wide awake at 3:30am.
