Ask as much questions as you want one day i was also a scared teen and I wished my parents or I came across this approach to stuttering. As to Tim, they work in the understanding that if I can speak fluently in one situation , I can speak fluently in all situations . Notice the situations where your girl can speak fluently ; maybe when she speaks to herself , maybe when she speaks to someone she feels same with . That means that there is nothing wrong with her brain or her throat or any organ in her body . Her body is perfectly able to produce speech . So what makes her throat lock up in social or tense situations ? Thats when we discover that stuttering is mainly psychological and thats what she and Tim will uncover in their therapy. Sure , speech techniques found in traditional therapy can be of help like slowing down and never forcing stutters , but they are only like 10% of the equation . The remaining 90% is the psychology of why we block when we were perfectly speaking well 5 minutes ago . Traditional Speech language pathologists are not trained in this, they mainly use speech techniques so they are working on the wrong problem . And for the price , you can try a session and go on from there , read his reviews on google , but please consider it an investment in your daughter's health and wellbeing because I am a 22 year old male and I wish someone told this to my mom when I was a hopeless 12 year old. For now , start with the book , start practicing voluntary stuttering , and go on from there. Good luck on your journey
