Traveller, did you do the course or just self-teaching?

Can anyone tell me, roughly, the cost of the hypnobirthing classes and how long it takes to manage the techniques? How many hypnobirthing practitioners are they in NSW (Sydney area), or just the one from the hypnobirthing website?

I just want to know few things before I decide to contact the hypnobirthing website.
I did a course for my 1st, a short refreshed course with my 2nd, and just revised on my own with my 3rd. I would definitely recommend doing a course with your 1st, it really helps with learning the techniques.
