My son is 6.5 and since he was probably about 3, he has demonstrated a stimming type behaviour that consists of running back and forth, sometimes accompanied by hands that flap loosely at his sides. He is NT as far as we know and he does not appear to have any other signs of neurodiversity. He is a happy, clever, sociable little boy who enjoys life. When asked why he does this, he says it’s because he’s excited. I think this is true as he does only seem to do it when he’s particularly excited, overstimulated by something he finds interesting or when he’s anticipating something exciting. Never through frustration, anger, anxiety etc. He is in full control and can easily be distracted away from the behaviour, and will often stop to come and join in with something that someone else is doing. It only lasts a few seconds to perhaps a few minutes at most. I think it just feels good to him to do it. He doesn’t do it at school, or at least he says he doesn’t, and it has never been flagged by anyone at school. He also only really does it when he’s somewhere open with lots of space to run about. My concern is that everything I read about stimming points to autism. Is it possible for a child to have these behaviors and not be ND?
