My son will be 4 next month and he also tends to stutter. He started when he was about 2.5 and it went away for awhile but has recently come back. Usually stuttering clears up on its own by age 5. Just let her complete her sentence. Do not finish it for her, or tell her to slow down or to repeat herself. I am not super worried about my sons stuttering but I am going to mention it at his 4 yr appt. You can search stuttering online if you would like to find out more about it.
