First Day of School

Well, Dreyton missed the kindergarten cut-off date by only 2 days and has to go to another year of Pre-school. I am fine with it though, I'm really not ready to let him go. He is having a hard time with it though and wants to go to Kindergarten soooo bad. All of his friends except one is in school. He is so bored at pre-school since he can already read alot of words and is a little pissed that he has to go when he is so bored. I am thinking of just taking him out and putting him in karate or something like that instead. Any suggestions from anyone??
