Hi Mama2OneSweetBun

I have some experience with stuttering in young children:
- it's not uncommon for children to experience periods of 'normal dysfluency' as their language develops. I bet DD has just started speaking in longer sentences, right? So the repetitions may disappear as she moves through this stage of development;
- but they may not. Don't draw any attention to it at all (i.e. don't give any feedback about the repetitions, although if DD is really stuck you could just say the word she is having trouble with to help her move on - don't do that if she doesn't like being spoken for!), but keep an eye out for the next 6mths or so, see if it improves or becomes more severe;
- if it becomes more severe, or if DD is bothered by it, or if you want a formal assessment, make an appointment with a speech pathologist at your local community health clinic. Even just a phone call to an SP will give much more *professional* advice.

Good luck!
