Has anything changed in your personal life lately, a move, divorce, have you went back to work as of late? When I went back to work my son missed me, and would want to do things like play in the middle of the night :) Have you started her on any solids yet...maybe if she has a full tummy she will go to bed sooner...unfortunately my son waoke up once or twice a night to eat no matter what solids we fed him until he was over a year old, sometiomes wanting to play, or be cuddled, etc. He also had ear problems so I think the more he sat up the more comfortable it was for him. Also, is she able to go in anyhting like a jumper or play table yet...I know the physical activity really helped him a lot with sleep as he got older. If it's any consolation after the first year he has been a great sleeper (like a rock), and an easy going child. He's now almost 4. I have an almost 5 week old, and she is actually a good newborn night sleeper, but she cries inconsolably every night for two or three hours before that, ah if we only knew :) Good luck, and I hope you get some rest soon.
