Hi David,
#1: Are you and your child going to use the Anxiety Advantage? I am certainly going to use it for myself - not for succeeding in swimming though 😉 but for several recurring situations during my business and other sports. I haven't had the opportunity to speak about it with my child but I certainly will. My guess: He might try but not tell me 😊.
#2: There obviously is no smart reason to not use it. The roadblocks in the beginning might lie in the visualization and creating a habit.
