I don't think having an aide in kindergarten is a good idea at all. Neither of my boys had an aide. Unfortunately, they need to learn their limits and have access to the kids so they can see the limits themselves. I felt that an aide at that point would start the isolation so young and then the kids would be afraid to play with them. If they start out like everyone else and they grow up with these kids like my sons have, the kids learn to accept them for their limitations and it becomes part of the everyday landscape. Yes, a few times some kids fell into my sons or they were inadvertantly knocked over but it was very rare. Neither one of my boys have aides yet and they are 15 and 12. My 15 year old is in a wheelchair but is self sufficient still and my 12 year old is still very ambulatory. Don't worry so much, I think he will be fine. One thing the school did was have trucks, sand toys etc out on the playground through like 3rd grade for alternative play that doesn't involve running etc. Truly he will be fine.. If he has an IEP he should qualify for Adaptive PE. My boys had adaptive PE at the same time of their regular PE and they would go to regular PE with the adaptive PE teacher and when they were doing things they couldn't or too hard she would take them to the adaptive PE area and do other things so they were participating with their peers when they could. This plan will also be in place next year for my 12 year old who will start jr. high. he will have adaptive PE at the same time as the regular PE and pick and choose what is appropriate.
