I posted this subject last August and am now writing an update.
My son is 5 1/2 now and is still exhibiting the same odd behavior that he has engaged in since he was three. For about thirty to forty-five minutes a day total, five minutes or so at at time, he goes alone to a room in the house and walks back and forth while making an odd and repetetive motion with his hands, arms and fingers close in front of his face. He holds both arms up at eye level and moves them up and down while waving his fingers. While he does this, he scrunches up his face. His movements, including the scrunching up of his face are always done in exactly the same way.
He finds it very comforting to do this. He says he "HAS TO" do it and that he uses him imagination when he does it - he appears lost in another world when he does this but I wouldn't say it's involuntary - more compulsive - like an obsession - a very comforting compulsive behavior. If he's watching a video, he will engage in this behavior in another room for a few minutes then take a break and watch the video then resume his behavior - he really enjoys doing it. When I ask him what he is thinking about when he does it, he says it's "violent" but when I ask him what he means by that he describes action figures fighting - that type of violence. He says it always has a good or happy ending.
He is in kindergarten now and does not engage in this behavior at school, however, within a half hour or so of getting home, he'll launch into doing it. If there are other children over playing, he'll go into another room alone and do it. He's figured out that it's weird so he knows to try to hide it. He will do it in public very occasionally when I take him out(if he's grown tired and bored of shopping, for example) and people will look at him and then me with a questioning look.
In every other way he is an absolutely normal, healthy, and bright child. He does well at school and has a very cheerful personality. He's 5 1/2 and is learning how to read. He truly is a joy! I just can't help wonder what this compulsive behavior is all about and how I should react to it. If I suggest he do something else, he resents it and tells me not to look at him.
Please help!!
