Yes, I thought he meant "unreasonable" too! Anyway, thanks Tracker. We are working on him understanding that it is very annoying. I really don't watch TV, so it is not really that, it is just the sheer sound of the noises is driving me and my husband crazy. I think sometimes he is doing it to get attention, although he gets plenty already. I have tried taking priviliges away, but then I wonder is this something he can't control. The other day though, I said I was taking him to a place to eat that he likes. I told him that if he started making the noises, that we would have to leave. He said "ok" and guess what? He didn't make the noises. So I don't think it is a tic.
Now, I want to work on him going into his room if he must do these noises. The problem is, his room is upstairs, and he is too big now for me to physically drag him up the stairs, and he won't go on his own. So, I am wondering if I should just quietly leave the room and stay in another room while he is doing the noises?
Bottom line is that I am not sure if this is a behavioral issue that should be treated with discipline, or is this something that he just really cannot help.
