He's not done!

S has his Developmental Therapy on Monday afternoons. He loves the Chunky Flash Cards from Usborne that his therapist always brings. If he gets started with those, it's hard to move him to something else. So, the therapist saved them for the end of the session this time. He likes making choices between 2 pictures (Do you want the sheep or the horse?), then she tries to get him to verbalize before she'll give him the picture by trying to say what it is or the sound it makes (He can do a very good elephant sound...of course, don't stand too close to him when he does it). Then he takes the card and places it back into the box. That seems to be his favorite part. He's very meticulous and careful when putting the cards back in the box (picture the game Operation). Well, evidently he wasn't ready to stop when her time was up on Monday. He started throwing a fit as soon as she started packing up. He followed her to the door and, as she was putting on her shoes, he said clear as a bell "I NOT DONE!". She said "Did you hear that? He just said he's not done!". I wasn't sure what I heard at that point. He proceeded to headbutt me in the leg, then ran to the living room throwing things and repeated it at least 2 more times through tears and yelling "I NOT DONE!" Needless to say, after she left, I broke down and cried. I've heard him try to imitate words and he has a few things he's been saying for awhile now, but a whole phrase just came out of nowhere! I then got him some of our cheapie flash cards to play with. He didn't seem to mind though. He just wasn't finished choosing and putting them away! :)
