We have noticed a difference in his speech since he's gotten his tubes. Some words that he has added to his vocabulary in the last week (I'm sure I'll leave some out): get, off, uh-oh, monkey (I swear he said that today), juice, drink, shoes, no (he still shakes his head to say no most of the time, so that's good. Except when he shakes his head while I'm singing - maybe he's trying to tell me something).
Tonight we pulled out the letter and number magnets for the first time in months. He arranged them in a very particular order and would get upset if I tried to help him or move any of them. I kept asking him what it said, and every time he would say "cheech". Interesting.
