The first time I noticed myself rocking was in my late teens. This was way before I even suspected I was an autismo. I don't do it consciously, and I only seem to do it when I'm sitting on the floor cross-legged. It's not like the stereotypical image of a hunched up autistic, clutching their knees to their chest, rocking and mumbling. It's just a very, very slight bobbing back and forth... I often don't even realise I'm doing it at first. And then I realise and I wonder if anyone has noticed. But I've never had anyone make any comments about it.
