Great! Thank you! It's so hard when at first teachers are telling you that he isn't playing with others. He does just try to join in sometimes as well without saying anyting, by trying to just hang out, or run along with the game or whatever; but someone most of the time seems to stop and ask what he's doing. It is so sad. I will definitely read that book. I have learned a lot just in the past few days reading some recent posts. My feeling is that he is possibly more mature, but reacts to things more intensely/sensitively which makes him seem less so. On one occasion when some kids let him play, he did shy away when it seemed to be getting a little wild or out of hand, and all of a sudden he was "it." He said "I'm getting tired," when he really wasn't. So he knew to make up an excuse on his own. We think that he is doing great otherwise. And on the rare occasion that a nice, older boy will act like a mentor to him in the park and play with him, it is awesome! Thanks again!
