hi ksy
i just also wrote on the other thread, but then saw this. I would not worry about a stim like jumping now. At a young age lots of kids do minor stims. if you went to my neighborhood pool in the summer you'd think half the kids were on the spectrum. Its one of those things that by itself is not a problem and will probably go away when he starts to feel self-conscious about it and notices others not doing it (see my other post). My son was also a jumper more than a flapper. I would not try to interfere with it too much as sometimes when you "put out" one stim a new one will pop up in its place, I'd just ignore it for now, and redirect him if its more than a couple hops.. I would also say that it might be a good idea to make an appt. for an eval even if it takes one year. That year may give clarity one way or the other, and you can always cancel. Also remember that we ALL stim in one way or another. I am a hair twirler.
