I cannot figure out this odd behavior. For no reason at all he stares at the floor, lifts his arms up and out like he's diving into water and goes head first onto the floor. He is not angry. He has been to the doctor and there is nothing physically wrong with him. He has bruises all over his forehead and has cut his lip twice. Once badly. What the heck child?! This can't be normal! Anybody else ever have this problem? It doesn't even exist on Google!
