Need some advice

My son is 4 and has spent the last year in a very good “school”.  He has made tremendous progress there.  However, everyday he screams his for me not to leave him there.  It rips my heart out.  The staff and teachers tell me its ok, he calms down within 5 minutes, that he “needs” to be there, to have the social contact with the other kids.  My heart and gut are saying something completely different.  I spend the entire day doing nothing until I can pick him up.  Most Autistic Mommies complain that their child has no attachment to them so I feel blessed that my little guy wants and needs me.  I started reading about CM this summer because I was going to start working with my son over the summer.  It seems like a natural fit for my child and me.  Am I crazy for wanting to take him out of a traditional school setting where he is definately making improvements?  So far this summer, its been going well.  Between park days we have been doing “school”, making our way through books, having fun with lapbooks, playing educational games on mommies iphone, etc.  I am almost certain that I want to keep him with me.  It just feels right (if exhausting).  Help!?!?!  A little encouragement will go a long way here.  Are there any CM folks in the Miami, FL area?  Thanks for listening.
