When you are ready to breath your baby down birth breathing just takes over. I sounded like a mooing cow ! the midwife thought I was mad

Its compleatly different to the breathing you use when having surges and you can't really practice untill you are doing it for real. What I can tell you is that during the breathing down bit of my labour I FELT NO PAIN. just pressure and did these funny mooing noises for about 20mins and had an 11lb 5oz baby boy

Try not to get into a fuss about the different breathing methods. Try and remember what Hypnobirthing is all about, letting your body and your baby do what they are meant to do.
