I am happy to report that Carter is doing well.  He has recovered completely.  He had a sore throat because they had to put a tube in to help him breath (standard operating procedure) and he had to sleep the last couple of days with his mouth open.  Today as he was napping I was watching (because I am a weirdo) and I could hardly hear him breathing.  He had his mouth closed and was not snoring!!!  Never seen that before!
