I am a 34 year old. I had a traditional stutter through school, it wore off as a young adult, and now I have a speech block, especially if I am one on one with a stranger, such as ordering food or interviewing etc. The amount of pressure that stutterers put on themselves can be immense, almost too much to bear. It is very important in my opinion that the child networks with fellow stutterers so that the weight can be lifted for a time. I also recommend letting the child watch their mouth with a mirror. I think you will notice that if you introduce a mirror indirectly that the child will look into it as he speaks anyway.
