I would put him in the program in a heartbeat. My kids were all peer models in an early childhood special needs preschool. Where we were involved, about half of each class was made up of typically developing peers. There were usually 4+ adults in the room at any given time--1 teacher, 2 aides, and a specialist or 2. In order to teach early childhood sped the teachers often have masters degrees. It draws a certain type of person and across the board they were such loving amazing people. The teacher student ratio was low and my kids all learned a ton. It gave me the break I needed to give attn to my school aged kids.
