One of my DS15 favorite activities for years has been to twirl a stick while daydreaming. Is this similar? It's kind of hard to explain. He has curtailed this behavior over the past 6 months and I asked him why. He said because he doesn't think it socially acceptable and since the only place we have for him to do it is the front lawn he is worry about what others think.

I've never seen any harm in it. He knows it's something he does when alone and helps him de-stress. Partly because I've always told him that he can't play with the stick with other kids. (It's like a broomstick length) I always figured it was easy to injure others with the stick, and a lot harder to hurt yourself.
