I have a 14 year old child who is autistic I also have an 11 year old who isn’t, for a while now my 11 year old has been what I would say bullying my older child. He speaks to her like shit, calls her names, is rude to her, makes her perform for him, makes her do things for him like get him stuff instead of doing it himself, he winds her up so that she has horrible meltdowns which can include throwing and smashing things and gets her anxious and in a bad mood which makes it difficult to take her out, ive told him to stop doing this many many times but he continues and ignores me, it may stop for a small time. Anyway I’m at the end of my tether with it all can other parents tell me what they would do in this situation, he makes her cry every day making my days more difficult than they should be.
