Don't get me wrong, I have the upmost respect of what you do, but if stuttering is not your specialism please be carefull. Lots of people with good intentions crossed my path in my schooldays, but only one really helped me. Some of them made my stuttering worse, because they missed experience. And if you have to ask on reddit.... this might be the case. I can't remember that I had one positive experience as a child regarding lessons/therapy/activities. Weather reporting, standup comedy... it would all sounded as pure horror to me as a child. What is "effectively using your voice as a tool "? it's sounds you teach them how to run before they can walk. I'm sorry this all sounds very negative. Please take this as constructive criticism. MySutteringLife is making a good point.
