My ds is 11 and autistic he used to be incredibly anti swearing until he started secondary school. Now he keeps swearing. At first I thought it was showing off as he did things like saying "fuck you" before hanging up on me when he called me after school for a lift. He lost his phone for that one but it's just getting progressively worse he tells his younger brother 9 to "go fuck himself" called his sister a cunt. He's been punished and lost his things but still carries on. He gets worse when he's stressed so he does it more when we are out and about and it's awful. I don't swear and can't stand hearing it from him not to mention the looks I get.
When he has a meltdown it's non stop "you mother fucking bitch...." Repeated over and over. I've spoken to him about it and all he says is "people at school swear and it's only words" I'm at my wit's end and don't know what to do.
