E.,
My son, almost 4, mildly on the spectrum, did best when we replaced his behaviors with others that were more acceptable. Keep things around that he loves, that you don't mind him putting in his mouth. (he will outgrow the behavior itself, Alex has had many odd behaviors that have come and gone: he isn't bothered by them, we are!) He will be safer, with things around that he can safely put in his mouth, just be patient as this behavior starts to fade away. In the meantime, try to find more acceptable rituals for him. For example, he has an obsession with his hands that is pretty bad; he also has a fascination for letters. We are teaching him the sign language alphabet - at least he can use that someday!
Good luck, I know how hard it is.
