This is true my parents to every speech therapist around the area and did it help a little it gave me some strategies to help reduce my stutter but I’ll still stutter until I hit the grave just help her find confidence in her self treat her as a normal human not something that needs protection 24/7 that’s what my parents did and now as an Adult I can go anywhere and feel confident in ordering what I want because you ain’t gonna be there for her always and she needs to learn that she is capable of speaking for her self hope this helps.
