So the last little bit my daughter (10 months) has been fighting naps and going to sleep at night. I finally noticed today that she fights and wiggles and pushes herself and cries until she can get herself backed up into the corner, so her butt and legs are on one side of the crib and her back and head are on the perpendicular side. Is this weird? Or normal? And should I be putting her there to start, or just letting her figure it out herself?
