I used natal hypnotherapy CDs for my first pregnancy/labour. I thought it was brilliant, used in combination with yoga breathing and moves and a hot bath.
I was in labour for 3 days at home, and was able to cope for all that time with the hypno, bath and yoga breathing. I was actually so calm that when I called the ward to see if I should come in they thought I couldn't be in proper labour! Fortunately I went in anyway, to discover I was already 5 cm dilated. I then made it to about 7/8 just with the hypno, bath, breathing. Then gas and air from 8cm.
My labour at this point was progressing extremely rapidly, and in what turned out to be transition, but the mw didn't realise at the time (prob because I was so relaxed), I asked for pethidine. Given the long time I'd been in labour they gave it, and I started pushing about 10 minutes later, which was unfortunate. Pushing took 20 minutes.
Mw were amazed how calm I was. I was in the worse pain I've ever been in, but I was calm throughout and didn't mind too much, and the breaks between contractions felt quite long. I screamed just twice in the entire 3 days (with the burning of the first push), but the mw asked me to concentrate on the breathing, so I did.
After the birth things started to go badly wrong with a severe tear and haemorrhage, and strangely I was complaining more about the tear pain than at any point during the labour (when I didn't complain once)! I think that shows how well the hypno was controlling the pain of labour, just wished they'd added a bit about pain relief for tears!
For me also the most useful was that although I nearly died following the birth I think the hypno helped me to remember the experience as positive. Everyone is amazed that I am not traumatised. I have been traumatised by something else and I know that fear/what you fear is happening is far more important in terms of longer lasting trauma, than the reality. So I think the hypno helped me avoid that.
I have to have a c-sec this time, and as that scares me I will use hypnotherapy again. I am even disappointed not to get a chance to put hypno against vaginal birth again!
