My ss is 7 and barely speaks, he has severe paranoia with sounds and will hold his ears even if he hears beeping, commercials, ticking, and even music.  He does weird things like touch his private area all day long no matter how many times you tell him to quit, we tried making him wear different types of underwear but he still does it and plays with his nipples (sorry i know tmi) so much that one is deformed now. He tries to touch peoples breats all the time even strangers and if we tell him to stop he will try to touch peoples arms and legs.  I tried talking to my wife and shes concerned too. She says he never did this before. She thinks it started after we had our daughter who is now 6 months old. She thinks hes just trying to get attention. To me this is just plain creepy. No matter how hard we try to set boundaries he keeps doing it. He only speaks like a 2 year old so it's hard to even discipline or him. He has this obsession with people hurt. Like if my daughter cries he starts laughing hysterically. I've even caught him trying to touch her nipples and laughing. It's really disturbing. I feel bad for my wife. Sometimes I catch her crying because she doesn't know what to do. I feel like his grandmother is a bad influence for him. Everytime we try to make him independent like eat for himself, we catch her dragging him down spoon feeding him like hes a baby. My wife said her mother might be the issue cause shes caught her walking naked in the house. When she confronted her about it she her mom said "he doesn't know and i was just getting dressed after I shower it's not a big deal" She has like no shame and will go to the bathroom with the door open and crap in front of strangers. My wife breastfeeds the baby but she covers herself and goes to the other room. I've heard that it's normal for autistic kids to be inappropriate but this feels like a whole other level. I never leave my baby from my side I'm so scared of him. I feel like he will never get better and I think my wife is starting to see it now too.
