can you tell us how old she is and what your daytime routine is? do you use Baby Whisperer methods? are you familiar with Tracy and her techniques?
if you can, please post your routine telling us as much as you can about when she wakes, when she eats, what she eats, when she naps and for how long, and what time you put her to bed. ideas about your routines around sleep times would be helpful to us so we can have a better idea of how to help you. as well, has there been any changes to her sleep pattern? is she old enough to be potty trained?
i know i am asking a lot of questions but there are lots of things we can consider with a bit more information. you have come to the right place, we will do our best to help you!
