Two weeks ago my son was attacked by another child at school (primary). Viciously.He came out ok, but honestly, it was serious enough that if a blow or kick had landed slightly differently an ambulance would have had to be called. His attacker is autistic, so it's not his fault and not about bullying. However, despite adult supervision, this happened. Basically, the child is very fast and very strong. In the two weeks since, my son has been attacked twice more by the same child. The second two incidents he was shoved to the ground. My issue is that despite the fact we were so lucky after the first incident that it wasn't so much worse, and despite awareness at the school and adults present, this child has made aggressive contact twice more. I have expressed my fears and stated the impacts this is having on my son in very clear terms to the school. I don't believe they can guarantee my son's safety even if they do their very very best. What do I do next? How would you handle this?
