Mom of a 9 year old stutterer who started at 2. Also married to a stutterer. I would be focusing on confidence. We can only do so much regarding their stutter but as parents, we have full control over how they feel about themselves. My 9 year old is in theater, and has performed for hundreds with speaking lines. He has friends, he's confident, and crazy enough doesn't want to lose his stutter because he feels like that is something that makes him uniquely him. Obviously working on the stutter is essential and important but I truly feel the most important thing we can focus on as parents is their confidence.
