Her doctor won't know anything about stuttering. The fact that she's not bothered by it is great. The biggest concern might be that you are very concerned. If you want to see someone, you should see a speech pathologist who specializes in stuttering. Even most general speech pathologists don't know much about stuttering. You don't need to tip toe around stuttering, but if you are concerned and don't feel comfortable about your daughter stuttering, I'd talk to a professional like I mentioned. Many kids who stutter do it around 3 or 4. Many other kids stutter around 10 or 11 and everywhere in between. Most kids grow out of it. The most important thing is that you daughter is not bothered, not embarrassed, and continues to talk her little heart out without fear.
