My 3+ year old grand daughter wakes up kicking, screaming, crying to the point of choking and ANGRY... but only after a nap. She is completely inconsolable, tells her parents she doesn't love them anymore, will not allow anyone to touch her or come near her sometimes for close to an hour and then suddenly snaps out of it. She often feels horrible for the way she acted and actually apologizes. Otherwise she is a normal, happy little girl. Mornings are fine, it is just after a nap that she acts this way. She has been doing it at least a couple years, maybe longer but it seems to be getting worse. Any ideas?
