I did a wise hypo hypnobirthing course and am currently 34 weeks pregnant. At the last session I did say I felt really unsure how to actually apply "hypnobirthing" in labour and my instructor was a bit like it's all in your subconscious- you will be fine. 
Today my husband and I were discussing it and I became really upset saying how I felt I had wasted our money as I had no clue how to "do" hypnobirthing. He and I both felt the course crossed over a lot with the NCT and stuff we already knew/read about.
Prior to doing the course I had read juju sundin and ina may gaskin, watched posative home births on you tube and had an all around good understanding of birth without fear, oxytocin, fight or flight etc. was I just too prepared and posative to pick up
Much from the course? The amount of actual hypnosis seems minimal and I've finished feeling frustrated and Ill equipt.
So tonight I had a look on Amazon as my husband offered to buy me another book but all three samples I downloaded to my kindle feature the same, just a small bit on hypnosis with a few affirmations or whatever and the rest is the posative birth stuff I already knew.
Are my expectations of hypnobirthing totally wrong? What actually is it? How do I apply it in birth and is it as simple as feeling posative and un fearful - I had this before the course so I've definitely wasted our money!
Any insights would be really useful- thanks
