Well, your posts confirm my suspicions. The first thing I started to notice, was that when I call his name or speak to him, he very very rarely looks at me. My first thought wasn't autism, but maybe a hearing deficit. My sister has never had his hearing checked and I thought it a logical explanation. I mentioned it to her and she says she'll have it done. But after all of the news reports, the reading I have done here, and the links and videos I have been watching about autism, he shows MANY of the warning signs. And honestly when I stop and think about it, he has been showing warning signs for a long time.....I can remember as early as less than a year old. He has never really engaged with any of us. I would play with him, kiss his feet, get down on the floor with him and play, and I don't remember him ever really playing back or engaging at all. He very rarely babbled as a babe and now at 2, I don't think I have ever heard him say one word. He babbles a bit and does say what I think is ma ma ma and that's about all I can understand. This doesn't seem like normal development. I babysat him last week. He frustrates easily. My sister has been mentioning with more frequency, he has meltdowns all of the time. She has mentioned it takes a long time to calm him down. I find myself thinking is it really just normal 2 yo behavior, testing the waters and asserting independance or not? When he gets excited, he shakes and moves his arms up and down ever so slightly. I bring my youngest who is 4 yo over to play all of the time. He occasionally will chase my DS or snatch toys from him, but that's it. He doesn't play "with" him, he plays around him if that makes sense. They have a dog. Last week I saw him look at a toy on the ground, he picked it up, made a face like you wouldn't believe, growled, and threw it as hard as he could right at the dog. He kept trying to do that and even after I would firmly tell him no, he wouldn't look at me or acknowledge me...just kept trying to do it as if I wasn't even there. I mentioned it to my sister and she said that he just started doing that a week or two earlier. There is more. But so far, what do you think?
