Stutterer and stuttering specialist speech therapist here, you’re already doing the best thing you can do. You’re caring for him and taking his difference into account for how you raise him. Just like any other skill or any other aspect of a person, you’ll both learn and change and you go and what he wants may be the opposite of what another poster on here wants. A parent who seeks advice is the same kind of parent that can have honest talks with your kid (later on of course) about how you can help in a way that they explicitly can advocate for. Some things you and your son may disagree on though… get him exposure, talking to strangers and family. No one who stutters enjoys stuttering, but everyone who has “recovered” from a stutter went through a phase of forcing themselves to speak regardless of their stutter. You can help your kid out by letting that be the natural way he is raised rather than something for him to learn in his early 20s like so many other people on this sub. Best of luck and feel free to PM!
