I seriously don't know what to do... gracelynne woke up at midnight for a bottle, gave it to her.. She usually goes back to sleep within an hour, but instead she has been up since then chewing on her hand, acting hungry but will not take a bottle... or go to sleep no matter what I do, I'm getting so frustrated.
