I have a 4 year old cousin named Alex. When he was younger we noticed he was different than other children. My aunt has failed to get him tested as she thinks he will grow out of it, but its pretty obvious he wont and she is denial. I think he is autistic because He can only say a few words and most of the time grunts and points when he needs or wants something, he walks around on his tippy toes, and has a hard time adjusting to change(he gets upset and throws a fit and can get violent; such as biting and punching) he seems very cold when it comes to feelings. If my aunt spanks him he doesn't react. And most of the time it seems as if he is in his own world(doesn't respond to his name) His hearing is fine my aunt had it tested. He doesn't like to eat but he still drinks out of bottles and still wears diapers. But for some reason he is really good at playing video games. My Aunts other son Devin has a touch of Autism. I'm just wondering if Alex has it full blown.
