hmmm, that is tricky since her days and nights seem to be switched. Does she have a good nighttime routine? i.e. dinner, play, bath, book, bed. Some variation of that...but bath and book help to set up bedtime. I would suggest as you are transitioning her back to sleeping at night to let her sleep in the morning for 2-3 hrs (between 9 and 11) then wake her if she doesn't wake on her own. Keep her awake and busy playing as much as possible until 2. Then let her sleep 1-2 hrs. Wake her up again if she doesn't wake up on her own. Keep her busy playing, take her outside or to the park. That should keep her awake (even if she's cranky) and also get her fresh air and wear her out for her nighttime rest. It might take all your spare time that first day or two, but I think it should be fixed pretty quick after that. Babies and Children in general need and crave structure. She takes her cues from you now. Once you set a good sleep pattern and routine in place, do your best to stay consistent. Good luck! I hope it goes well.
