Is she full-time? I have a baby girl right now who had terrible separation anxiety because she and her Mom hadn't been apart for a day or night since she was born. When we were easing her in 2 days/week it was absolutely horrible and she cried all day except for meals and nap. Then when she became full-time after about a month it took a couple more weeks of crying like that then she started jumping into my arms in the morning instead of just crying on her Mom's shoulder when she saw me. Now she's really happy here.

I was lucky that she's my first arrival so I would spend a bit of time hugging her when she arrived and playing little games and songs with her so we had our bonding time before breakfast and the arrival of her friends. Once these little people trust us they are happy. Can you do something like that with her?
