I stim a lot, which was a surprise cos I didn't know what it was til recently.
Swinging on a swing til my legs are jelly is my favourite, but I can't do it often cos I hate the cold and wind and swings are always in exposed places. Great when my kids were young, I could never understand why I was expected to chat with other mums instead of swinging, got some odd looks, but there is no contest which I would rather do!
When I walk my arms want to rise up and fly, the faster I walk, the more they want to rise. I do it in work, no-one seems to have noticed, but it helps me not get so stressed if I feel free like that.
Leg (or foot) goes radidly up & down when I'm sitting waiting.
I bounce up & down when I'm happy.
I love singing, it absorbs me totally & I won't break off mid-line if the kids ask me something, they know to wait til I'm taking a breath, then I can answer.
My sister & I twirl our hair in time with each other, without realising, until someone points it out.
I didn't realise this was unusual, most people in my family do it, spinning, bouncing, finger cracking, tickling your own arms, rocking while watching tv, legs going, etc.
Doodling is another understated stim, its really hard to know what is a stim and what is not, I count doodling and singing because they feel the same as shaking my feet etc the difference is in where its appropriate to do each one.
After my son broke his third bed bouncing we bought him a trampoline, he can do backward somersaults for an hour hardly stopping. If his drumming on the table annoys me I tell him to do it in the air instead so its quiet, is that hand flapping? He says "I've just got to move my arms". I thought all kids were like that!
My mum was big on stimming too, hole in the carpet from spinning on the spot, so I guess we have a long history of acceptance
Stimming is as natural as a dog wagging its tail.
