This was beautifully written. I think you are absolutely right that the inherent fear of fidget spinners is tied to the NT discomfort with stimming. My two kids did a bunch of chores this weekend to earn the money to buy the exact spinner in the picture above. They arrived yesterday. Sitting in the car at the school waiting for the kids to come out, I opened them both and tested them out to make sure they both worked. Oh, it was a good feeling. Once my son got home and tried his out on the floor, he instantly began hand-flapping and toe-walking. I can’t understand how people can know what they know and still have a problem with stimming, but I know that so many do.
I will note, however, that my daughter pointed out a few reasons that fidget spinners were banned in her own classroom. She said there were perhaps five kids in the class who were bringing them. The other kids were constantly asking to borrow them, fighting over them, trading them, etc. So it wasn’t the use of the fidget spinner in the first place, but the other kids adding the complication that ruined it for everyone.
