My difficult child has a habit that he's had for years and years. Unfortunately, I think husband and I have gotten so used to it that it's part of difficult child's demeanor. That doesn't mean that we aren't aware of it and I tell you, it bugs me to no end. difficult child pounds, taps, kicks on everything all the time. I wonder if it's more of a tic? We sit at our kitchen counter for all meals and everytime he sits there he's kicking the counter, or tap tap tapping on the counter with both hands on each side of his dinner plate, or using his knife to ding ding on his beverage glass, or shaking the table at a restaurant. We remind him over and over and over to STOP!! It's maddening. Even after being reminded he can't seem to stop for longer than 60 seconds. Even after all these years it's very annoying. Do any of your difficult children do this? How can I get it to at least lessen?
