Have name changed. My 6 year old son wants a full class party for his 7th birthday in August. The class are really nice and all get on well ... aside from one child. I don't know if he is on the spectrum or not but what I do know is that every day he is physically abusive to the other kids - but mainly the girls. He has only punched my son once but some of the other kids have had continuous physical abuse from him on a regular basis. My son doesn't want to invite him to the party at all - which is if course an option - however I would feel bad not inviting one child - and before anyone says anything I am not going to have a scaled down party just because one child doesn't behave - that's not fair on my son or the other kids. However I don't want to carry the responsibility of watching him as I will have 30 other kids to watch over. I also don't know how to deal with the child if he starts behaving like this. AIBU to say to his mother that I need her to fart to ensure there are not incidents?
