S., when I was a newlywed, my husband had a friend whose daughter (about 6 or 7 yrs old) stuttered. They'd been taking her to counselors, and weren't having any luck. My hubby & I decided to try taking her to our house a day or two each week, as we perceived that as the youngest in the family, she might benefit from being the "only" for a few hours a week.
We lost touch with the family for a while, and about two years later, they called and begged us to come for dinner. We were sitting and laughing and talking and I kept feeling that I was being stared at. Finally I asked point blank, "What am I missing?" and the mother said, "Kathy isn't stuttering."
Oh my goodness, I was so excited for her, and so proud of her and I hugged her and apologized, telling her that it seemed so natural to me, that I had totally forgotten that she'd ever stuttered.
Her mother said, "But it's you and Terry who got her through it!" I must tell you that I was shocked. This dinner was Kathy's "thank you" to us.
All that Terry and I had done, was to stop what we were doing and listen to her and let her speak. We had thought that she was very shy and unsure of herself, and all these chatterers around her made her keep feeling that way. So when she'd begin to speak, we'd give her our full attention and we wouldn't finish her sentences for her, so she got more and more comfortable with knowing she didn't have to hurry up and spit things out. And I'd hug her a lot. But mostly, it was just that we would listen with attention and show her our pleasure at having her talk to us.
When we'd take her home, her parents watched how she was talking with us, and noticed an improvement in her. And they started trying to copy us. Terry and I weren't aware of that. It seemed very easy for us (she was darling), but when we'd have her for a day or two and take her home, her parents saw a change.
I know this is nothing that you will probably ever see in a medical book. And we reacted from something within us that "recognized" something going on in the family that was hard for the little girl. I hope I am correctly remembering her name. I think of her frequently, but it was almost forty years ago, and my memory is horrid about details like names (even current friends, lol).
But I do really recommend that you not finish the child's sentences, not try to help her spit it out, and look at her with your full attention and a gentle smile when she begins to stutter (to not let her think you're worried ... and you should NOT worry!) There are many ways for you to help her. If it grows worse, perhaps see if she can sing the words. Make sure she knows that she must be one of the special people who is meant to think before she speaks (something that many of us grow to lament we forget to do).
And at her age, she is very young for you to worry about such a thing. When our children are just learning things, and it seems that they aren't quite the same in their abilities as others, that's the time that we should stop and look at them and let our imaginations soar with interest. We should ask ourselves what this is going to mean for them as an adult (in a POSITIVE way), and we should help them to achieve it.
Blessings;
