My 4 1/2 year old DS has a much beloved plush panda. It is his security object, his sleeping partner, the animal he takes to the dentist's office, you get the idea. Frequently at night when we are settling down to sleep, panda hits him in the face. I.e. he uses panda to hit himself, then cries because panda is hitting him. I do not believe he is actually hurt by this -- its a stuffed animal and not even a very big one at that. I can't figure out if this is just unusual but ignorable or a sign of something else. Any thoughts from you guys?
