People keep coming at us to give "advices" or bad "solutions" so we need to remember. That the outside of A, A, T (Acceptance, Accommodation, Therapy) is danger zone. And parents of stuttering children should remember that there are bad adults who target disabled children and they will start with small things to earn your trust. "this little thing X will help your stutter. Just do X." And gradually, "just do X" becomes "just do Y", and that becomes "just do Z". It's gradual so you wouldn't notice what's at the end of X, Y, Z. So the line should be drawn as soon as it's something outside of A, A, T.
