Of course ! but lets follow the logic through . Assume the kid is happy as larry flapping away but it stops him from learning . Do you redirect or do you leave it ? I think the answer should be the same as what you have said . FWIW I think that is why ABA programs work on that because it can impede learning . For that purpose i think addressing stimming is ok . Doing it for asthetic purposes or for austistic kids to conform or look normal I agree is total bullshit . PS full disclosure I never wanted to stop my son from stimming . But seeing the relief on his face when he learned how to stop himself was like watching someone in pain be given morphine pure relief <| sep |> If you can ' t return the gap one , I would say that right there should stop your wondering if it ' s worth it or not .
