My eldest son is 10 and has Aspergers and ADHD.My youngest son is seven and is having problems and school and home similar to my eldest son. The school want to have him assessed which I am fine with,but feel I am missing something as to me they are so different to each other. My youngest son is affectionate and holds eye contact, he has very bad seperation anxiety, also he doesn't have special interests. Can he also be on the spectrum??
