A.M.
I have one suggestion for you. We recently went through/are still somewhat going through something similar to what you have described with our 15 month old. We have multiple issues to contend with, but assuming that nothing was truly bothering our little girl, our pediatrician suggested this method. When she wakes--and you know that she is truly awake, but not waiting until she is so upset that there is no going back--go in and stay with her for no more than 10 minutes. Our daughter went through 2 ear infections and is still getting 2 molars at the same time, so he also recommended that we give her Tylenol and Orajel to help alleviate any pain--obviously, if your daughter is not, then you wouldn't give her the meds. Follow your normal "go to sleep" pattern, then leave the room. Do not stay for more than 10 minutes; if you do, that signals to her that it is time to get up. All you are doing by going in is to reassure her that she is not alone and that you truly are nearby. She may cry again for a while, but we have found that it is more of a tired cry rather than an angry one. Each time she has gone back to sleep.
I hope that this helps you to some degree. A cranky, tired baby always creates a cranky, tired mommy. Good luck.
