My son (ASD and 3.5 years old) is constantly making noise. It does not bother me in the least and I've never tried to redirect him.
He hums, he sings, he does the drumbeat to songs using his mouth to make drum and cymbal-like noises. He says, "do do do dah" when he doesn't know the words to something.
His OT last year (who we no longer see) thought that he only did this when she asked him to do something he didn't want to do or thought was too hard. I disagree. He does it constantly, when he's happy, when he's upset (it just gets louder), when he's busy, when he's bored, etc.
Today at preschool they said he did it for the whole 2.5 hours. I was not surprised. What surprised me is they said this is the FIRST time he could not be redirected. Normally they ask him to be quiet and he obeys them. Now, THAT surprises me! Maybe because I've never asked him to stop?
Anyway, I guess this is a behavior that is not appropriate at school? What can I do about it?
I have no problems with him doing this at home whatsoever.
