If my Autism Spectrum Disorders (ASD) kid were getting taunted on the playground, I'd demand an aide for him and remind them that if my child is damaged physically or emotionally they are responsible. And I'd get the aide. Playground supervisors have no idea how to handle "different" kids. My sister is a playground supervisor and she sees all "different" kids as troublemakers with weird parents. She has no training with kids other than she's a mother. I doubt any of the supervisors on your child's playground know diddly about your child. I hope you get this resolved. It bothers me when "different" kids are egged on and then THEY get into trouble.
