Fluency isn't what they mean by excellent communication skills. When they ask for excellent communication skills, they're not thinking about stutterers, theyre thinking about the fluent people with horrible communication skills. Ergo, stuttering and excellent communication arent mutually exclusive. If you are intelligent and have people skills, show it. I stutter a lot but my personality shines through that and people see it and they like me. I know a lot of accountants and CPAs who work for big 4 firms and other respectable places. They dont care that you stutter, they care that you can do the work and you can communicate. You dont have to be fluent to communicate effectively. As far as your son, you can't learn stuttering. It isn't a contagious behavior they can pick up by hearing you stutter. But they can see how you deal with it and how it affects you. So whether they end up stuttering or not, you want to give them a positive stuttering role model. If he thinks stuttering is bad, it'll be because he's seeing it portrayed as a bad thing. Imagine if you just let stuttering happen and not feel ashamed of it. He'll just see it as "that's how daddy talks".
