I'm convinced my 4yo ds1 is on the autistic spectrum. He has obsessions and rituals, extreme tantrums if we don't get things quite right, would cry if a stranger talks to him. I've read a little bit about it and he ticks all the boxes. HV has been on the scene ever since he was born because I had PND and PTSD following the birth. We also have medical problems with ds2 so the are keeping a welcome eye on us. I recently suggested ASD to HV and she is convinced the root of the problem is me. She is coming back tomorrow and I am wondering should I push the issue and risk looking totally bonkers / incompetent as a mother or let it slide til ds1 hits school where they will probably pick up on it. How important is it to get a diagnosis asap?
