Some of the comments in this thread are phrased in a manner that's misleading. There's no guarantee that a person with a stutter will pass on the stuttering to their offspring. What we should be saying instead is that there's an as yet not fully understood genetic component to stuttering, but this is by no means the only factor that's at play, according to the research that's been done so far. As we know, genetics in general are not machinistically deterministic - there's always many factors at play, and stuttering is no different. - Bottom line is - we can't tell you if your kid will have a stutter. We also can't tell you that if your kid starts manifesting speech inconsistencies, that they'll grow out of it (which is most often the case in language acquisition and development). We also can't tell you that even if your kid develops an actual stutter, it'll go away eventually (which is often the case). We also can't tell you if your kid will live a happy life despite being a stutterer (which is indeed possible), or to which extent a stutter will have an impact or take up space (which depends on the case, the person and their path). - So the _real_ bottom line is - we can't tell the future. So if you say in advance it'll inevitably be bad - you're not being truthful. That's just fear talking.
