Thank you. I have read Hendrickson's book some time ago (I believe when he made it available). After finishing the book I couldn't find anything that might be important enough to highlight. So, I decided not to summarize it. I am currently summarizing [this research study](https://direct.mit.edu/nol/article/2/2/308/98521/The-Role-of-Sensory-Feedback-in-Developmental) ("The Role of Sensory Feedback in Developmental Stuttering: A Review" (2021)), and I'm extracting tips from it so that PWS can easily apply them
