I can understand why you might feel bad at first, but stuttering isn't that bad of a problem to have. My dad stuttered and so do I. My brother mumbles. I expect if I have a male child he is likely to stutter. People have to work through all sorts of things growing up. No one is free from that. If it's not a stutter it's something else. He might grow out of it or he might not, but in my opinion it's nothing to be worried about.
