I think that the word "concerned" makes it sound like someone being a person who stutters is a bad thing. I have a husband and two kids who stutter- when my kids started stuttering, I was worried that they would be self-conscious about it or that it would negatively impact their self-esteem. But I wasn't concerned for them. I love them and I'm proud of them. And so far, they both have days where they stutter more and days where they stutter less, but they don't look at stuttering as a bad thing, just a part of who they are- they are both proud of the way they talk.
