K.D.
I myself stutter. I have my entire life. As does my father and his brother. Yet, I've managed to give countless presentations, earned an MBA, and now recording my voice for web-based tutorials!
I agree with another post, that you should communicate with the child as naturally as with anyone else - continue eye contact through pauses, don't talk over them or finish a sentence, and be patient. As the child grows, teach them about the "mechanics" of stuttering - how it happens and why - so that they detach their self-worth from the poor speech habit. It's my understanding that stuttering, for many, will never go away completely.
Also, in my experience, as a child gets older, the stutter will worsen as anxiety about the stutter worsens. As a young adult, I've found that techniques oriented towards relieving anxiety are the most effective way to manage my speech. And part of that is not getting stressed, anxious or scared, when I stammer or stutter over a word.
You can probably tell I'm passionate about this and am convicted about what ought and ought not to taught to a stuttering child. But I'll stop here :)
Good luck!
