I've thought about this, and given the psychological nature of it, for me the focus on it made it worse. I stuttered more after speech therapy than before. One of my kids had a hint of a stutter as a kid and I forbid speech therapy. Schools offered year after year and I always said no. She's a junior in high school and doesn't even have a hint of it now. Let him grow out of it. Putting pressure on it will make it grow in his head. Speech therapy is so far off base. Almost every stutterer does not stutter when alone. Yet they only focus on mechanics in speech therapy. It's a psychological problem, not a mechanical problem. Mechanical therapy makes the psychological problem worse for me because it feels like pandering.
