Meags, yes you attended the course, but unless you had listened to the rainbow relaxation daily for the last 3 months of pregnancy (which I know you didn't get on with) practised the breathing daily, and had a specific fear release during your pregnancy about your upcoming birth, then you couldn't expect to see the benefits of the techniques.
Because of your background and your exposure to birth before your own, any imprint of pain would have been a significant one. As you would know from the book and course, any negative images of anxiety of any kind can affect the birth process.
You had the birth that was right for you and Matt, I'm not saying its wrong that you didn't practice the techniques - it's not for everyone, and besides when you attended the course it was in your capacity as a midwife and not a mom-to-be.
BUT it is really important that women that are interested in HB understand that achieving a pain-free hypnobirth comes not by just reading the book, or attending a course - there is a lot more to it. Remember my analogy of weight watchers? I just give the moms the recipes, it is up to them to use them or they won't get any results. ONLY the mom is able to take herself into a relaxed state on the day and that comes from weeks of practice.
I hope that makes sense and you don't think I am dismissing your comment or experience - just trying to explain why it would not have worked for you
