Another mom of an almost 11 yr old stutterer. He too refuses to use the techniques. He is already medically complex and uses a wheelchair. I’m not overly worried about bullies because who’s going to make fun of the kid in a chair? Plus he’s just the sweetest and everyone he meets is happy they met him. And while it’s very exhausting and frustrating for us as his parents, I can’t force him to use the techniques and he says he doesn’t feel like he needs. He does but he’s confident. I don’t have any advice but just sharing you and him aren’t alone.
