A good resource for people who stutter is the Stuttering Foundation. There’s a wealth of information for teachers, parents, and kids.
A link I posted on my Facebook yesterday that I found particularly helpful: FAQs for teachers
There’s also free E-books and videos as well as pretty deep resource list
Their mission statement sums up what they’re all about:
“The Stuttering Foundation provides free online resources, services and support to those who stutter and their families, as well as support for research into the causes of stuttering.”
It’s a great site that provides great help, and I strongly recommend taking some time to explore its pages.
