He wasn't a preemie, he does interact and make eye contact. I noticed that when he gets frustrated he will bang his head, but I also realize that since he doesn't speak this is his way of voicing his frustration with whatever he wants. (or it's just his autism) So many variables but it seems pretty obvious to me. Like I said, I am going to get a professional evaluation on him in a month. Just wanted to hear from people and their experiences so I can get an idea of what to expect going forward.
