Hi. My boy is 9,5 months old. He is crawling and sits unsupported. I started to worry because he is keep rocking himself back and forth before sleep and now he started to do it for example after playing also rocking left and right. He doesnt point, wave, clap, doesnt look in the directions i point. When i smile he smiles back when is play peek a boo he laughs. I m really scared that he is coming up with signs of autism. Has anybodys child did this ?
