Im hoping someone can reassure me. My son had just turned 8 months and is constantly twirling his hands/wrists, more so when he is excited or frustrated, he also opens and close his hands at the same time. He is not yet babbling mamama or dadada but does make noise with vowel sounds/shouts/laughs. He has just learned to sit by himself, although is still a little wobbly. No crawling or any gestures yet. His eye contact can be good but he can also look past you/ignore you. He’s not really responding to his name yet either. I know it’s too early to hugely worry about Autism, but I am, and I can’t shift the worry. I’m hoping that he will start to babble soon, and that the hand twirling is nothing to worry about, but I’m just wondering if anyone else noticed this with their child and what happened as they grew older?
