My son is currently awaiting a diagnosis he is 3.5yr old. Whenever he gets ill, he stims a lot more. However his physical and violent outbursts get a lot worse too. Biting, kicking, pinching, scratching, headbutting, spitting etc etc. I don't know how to help him, I've become quite black and blue and although I have great patience, I do feel sometimes I am close too losing it and feel so guilty for even those thoughts. He can't help it, I just need help for him, so I can understand him and the system is so broken it's crazy.
