I used the natal hypnotherapy cds.
With Toby i started listening to the "birth preparation for hospital/birth centre" cd at around 32 weeks and built up over the weeks, he was born at 38+1 by which point i was listening to it at once every other day. I didn't listen to the cd during labour though OR the relaxing birth music cd which i'd bought and put on my ipod
Labour didn't go to plan anyway though so not sure if they'd have made much difference if i had listened to them by that point? (If that makes sense at all?!) I still have a very positive birth experience- just not what i'd had in mind, AND, most importantly for me i think, i was never afraid in the run up to giving birth, no matter how much people told me it would hurt or how many horror stories i was told, i was so looking forward to the experience and finally meeting my baby, so for me, first time round, even though it didn't impact the birth, i still felt it was worthwhile as it helped me relax and stay positive in the final weeks of pregnancy.
Second time round, with Rudy, i started listening to the "home birth preparation" cd earlier in my pregnancy and built up quicker. By the time he was born at 38+4 i was listening to it every single evening without fail.
I also bought the labour companion cd this time and i still had the relaxing birth music cd. I listened to the birth prep cd in very early labour, then when my contractions were strong and regular i tried listening to the labour companion cd on my ipod but couldn't get into the rhythm of it at all. I was soon to discover that was because i was listening to entirely the wrong track as i was much further along in my labour than i'd thought but i didn't know that at the time, so i just ripped the headphones out and told OH it was bugging me! He suggested switching to the relaxing birth music instead though and i agreed and found that immensely relaxing
A short time after i switched to listening to it on the cd player instead of headphones so that the whole room had a really calm feeling and also so that the headphones wouldn't keep falling out of my ears and bugging the crap outta me!

I had a fantastic labour and birth, going from 2cms to baby born within a couple of hours. I also managed with just a tens machine and 2 paracetamol taken about an hour before i gave birth. It's an experience i'd happily repeat tomorrow. I think a large part of how brilliant it was can probably be accounted for by the fact it was my second baby and that i was at home etc BUT i do think that natal hypnotherapy helped me get in the right mind frame during pregnancy and in very early labour
