soccer and aspergers- Whats a mom to do.

Well I bit the bullet, I have officially enrolled Mateo into soccer, against my better mommy judgment. I understand the need for him to be challenged, I also get that this may help his balanace. But any mother with a aspie child knows that sports don't really go in the category of something their child can do. Sure Ive looked everywhere for someone to tell me " Hey my kid does just fine". I have yet to hear or read that. I am worried, I am scared that he wont know how to play, he will get hurt, or the kids will leave him out. Trust me kids at 5 and 6 are brutal, and my son wouldn't hurt a fly (most likely because he is afraid of flies). So with us luck, Thursday is our first practice.
