I was just told yesterday that my 2 year old son failed his M-CHAT (the questionnaire they give you to determine whether they might be on the autism spectrum or not). Obviously I don't have a real diagnosis of anything, but I also won't see my pediatrician again for almost 3 months, so looking for some advice. He's been in speech therapy since 18 months, since at that time he could only say mama and dada, but didn't know what they meant. He can say a lot more now (somewhere between 50-100 words), but still only nouns, really. When he wants something, he usually screeches and we have to guess what he wants. He doesn't point much, except to pictures in books. The biggest red flag for me is the fact that he never does imaginative play. He prefers repetitive tasks, like putting Cheerios in a bowl, dumping them out, and putting them back in, or stacking or lining things up. We got him some toy cars, and instead of driving them around like my DD will, he brings one to me and wants me to open the doors so he can close them, and we'll do that over and over again. He smiles a lot, though, and will make eye contact with us, although sometimes he'll run towards me with his head turned, looking in a different direction, but I've always assumed it was just his way of being silly. Any thoughts?
