I need some advice I really don't know what to do. I have been split from DS (6, ASD) for almost 6 years now. We split because he was aggressive with me. Ok horrendously. He has never ever been aggressive with DS. DS goes to see him and his girlfriend on Friday nights Saturdays and today he has come back with 4 red marks on his shoulder. To me it looks like finger marks where someone could have grabbed him. It's like a pinprick type bruises like pinpricks joined together but 4 of them.
I asked his dad if DS had needed to be grabbed because of falling, running off etc. he said no and if I was on about a mark he had it when he came to him. I then mentioned that he had been swimming at school Friday (special) and staff hadn't mentioned it and I drove him straight to his Grandads (paternal) from school and changed him there and it wasn't there then either he said oh he doesn't know he hasn't seen any bruise.
I don't know what to do. Do I do nothing? Mention it to school?
