Ethan discovers he has a head

Last night, while Steve and I were cleaning up from dinner, Ethan fell asleep in his aquarium bouncer. He was sucking his left thumb with the other four fingers pointing up towards his eyes. And for a long time, his right hand would start off feeling his face, forehead, then up over his head, around his ear and back to his face. It was the first time we have seen him touch his head (other than his face).
