School?

My little beanie baby is going to be starting school in september. Hes going to be in a classroom with other children who have developmental delays for whatever reason. I know starting school early will greatly benifit him but i can't help but feel bad cause hes so young only 2 and a half and hes so little yet. I had a hell of a time even finding him a back pack that wouldn't over take him. Chase seems excited about it though he loves other children and he will finally get the bus ride he always wanted. I'm also worried about the other children. Kids can be very mean and Chase looks different.. no helmet anymore but he has a very visable scar and wears a patch on his one eye and keeps his left hand balled up in a fist for the most part. Already when we go out kids constantly ask about his head or his eye. Chase of course is too little to understand and bless his little heart he is still a very happy and outgoing and loving tough little boy. I'm probably just overreacting.
