B.C.
If she wants to stay in her crib, let her. There are lots of battles to be had, and where she sleeps shouldn't be one of them if she is safe and comfortable. Do you need the crib for another baby or has she climbed out of it? If she hasn't climbed out of her crib and you don't need it, just let her stay. She might only be in it for a few more months before she decides to use her big girl bed. As for the potty training, that takes a while to get them dry throughout the night! My three year old still wets at night. I think it is around 4 when they start waking up dry consistently. Good luck with whatever you decide!
