A good friend of mine's son was like that, but he didn't even babble, he just wouldn't talk! Or he'd say, "NO" or something. If I talked to him he'd just STARE at me and not respond. They were from out of state and when they came here I took them to the beach - the kid wouldn't leave the blanket, he got REALLY upset if he got sand on himself, his mother had to take every bit of sand off him (I know autistic children will have a very acute sense of some kind and get upset, I was CONVINCED he was autistic!) The next year when they came over this kid was a totally normal 4 year old - talking like he should, etc! Today he is about 17 or 18 - VERY intelligent young man.
