My son hums alot. It is a loud, deep hum. It almost sounds inhuman. If we are in any room and he begins humming everyone checks their cell phone to see if they left it on buzz.
It has become very comforting to me....this hum. If he is humming he is trying to control the screaming. We worked hard to get from the screaming to the humming. Every time he would scream, yell or blurt out we would try and replace it with a hum. We would model "Ommmmmm", "Ommmmmm". And after 15 years of behavior modification he would repeat what we did. We (my son's team, yes, we need a team) thought the incessant yelling was a stim, so we wanted to replace the stim with a more appropriate stim.
After a month of "Ommmmmm"ing constantly I know that I feel calmer. Maybe I have changed my vibration and am now zen. totally zen that is until the humming stops and the screaming starts.
When he was 4 he hummed straight for 2 months. It made me crazy. Now I don't get it, I wonder how in the world did that tiny, little, hum drive me crazy. Perspective? I would give anything to have that sweet, soft, hum back. When he was 4, I could pick him up and carry him out of places that were not friendly. I could hold him tight against my chest where only I could hear that tiny little hum. I should have appreciated that hum. I should have never, ever have let that hum drive me crazy, I was just afraid it would not get better......and it didn't.....it got worse....but the fear of the inevitable made me not appreciate that beautiful sound. I try and remember that. When anything gets difficult., I think of that soft little hum, and I am grateful FOR EVERYTHING.
