Hi!
I had my first baby (DD) in september and used hypnobirthing. I had a home water birth too! I absolutely loved it and firmly believe it influenced the way my birth went massively.
The classes were interesting and fun, i loved the fact that my husband came too and we were both on the same page about the birth, the techniques are really good and it really brought us even more together practising them.
For me, although i had a few birth fears (which you can talk about etc in class and work through) i felt confident in myself and my body to have the labour i wanted.
My husband felt confident about it too and it showed during the labour, he was calm and loving and his trust in what i was doing gave me extra strength and security.. (and for a 23 year old i think that is good!)
During the first half of the labour i was more active, the the midwives came and i was at 5cm and got in the pool, that was the time i really used the techniques, i deeply went inside (as best i could) and allowed the labour to happen, i was pushing within the hour.
Was in active labour about 4 hours and it all went very textbookly! I even caught the baby myself in the pool and brought her into my arms.
I will deffo be using it again for my next birth, am not saying labour wasnt EXTREMELY intense haha but i definitely was able to cope and didn't need to use any drugs - gas and air etc.
My one tip is to practise practise practise the techniques and listen to the cd every night when you go to sleep! I think that conditioning of the mind thing really works and because i associated it with relaxation when i heard it in labour i just went to that place as best i could!
Good Luck!!!
