Hm. I’m not sure what type of stuttering I would have then according to your perspective. If someone stutters as a child, or develops stuttering as a teenager, or even an adult, I feel like it is all the same type of stuttering. I believe we all are sensitive to our emotions and that emotional reactivity causes muscles tension (stuttering) which either increases or decreases depending on how much we care what other people think about the stuttering. I think some people that began stuttering from their first words as a baby believe they have a special type of stuttering, but my perspective is that it is not special. It’s just that the stuttering developed earlier in them opposed to later for some. As a baby, the way we interpret the world is so limited. But as we get older we can learn to filter the world in a more conscious way. And overcome emotional sensitivity/process our emotions more efficiently. Then stuttering can be overcome at least to a good extent.
