If you spend any time with families with autism, you will either hear about or see stimming. What is stimming? You have to watch the video for the full answer.
My children with autism stim. My son likes to have a block like toy in a plastic bag that he constantly manipulates. He started with the toy in a sock, and he sometimes still includes socks, but it is the bag that is most important. We have to hide the sandwich bags when he visits or he will use them all. Our daughter has her own form of sign language. This is no official sign language but through it we can tell when she is really happy or really upset.
This video by a person with autism does a great job of explaining stimming.
