I stutter and my father did too—so not exactly your situation. BUT if there’s one thing I learned is that people have different forms of stutters and different personalities and experiences to help them make sense of their experience. Be supportive, of course, but try not to project your own experience onto your child—he might view this very differently from you, and have a completely different experience because of it. Also, I wonder if this experience is triggering your own trauma with stuttering. Please take care of your own pain as well. Best of luck!
