My 16 year old brother has started to poop his pants. He's never done this before and he try's to hide it. My mom confronted him about it and he told her that he was playing a video game and didn't feel like going to the bathroom, so he just pooped I. His pants. My mom told his psychiatrist, and she said its because of his autism. I'm having a hard time believing that though. I'm also autistic, and I don't poop my pants. My brother also has Tourette's. I feel like he's got behavior issues, and that's what caused this pooping thing. Please understand I'm not saying he's not autistic, just that I don't think autism caused him to poop himself. My question is am I wrong to think this?
