I did first with (induction) and second without (spontaneous).
I decided after #1 I definately didnt want one with #2 and this was further confirmed after being my sisters birth partner.
I found that being on my back on a monitor meant the whole thing took way longer than it needed to. I wanted to use gravity this time. Now dont get me wrong - epis are magic when they work properly and mine worked perfectly but it meant it took bloody ages (16hrs HARD labour) and I was too shagged to push properly so it was forceps to pull her out.
Watching my sister go through her labour a year ago reminded me why I didnt want one again. She did so well and I tried briefly to talk her out of it but it was her labour and her baby so her choice not mine. She had the epi and laid there for hours not getting anywhere, too knackered to push, failed forceps and emergency section. Of course that aint gonna happen to everyone but it was our two experiences - the plus side was she was awake for the section.
This time I wrote in my birth plan 'dont give me an epi even if I scream for one which I probably will!' Of course 45 mins before she was born I was screaming for an epi!!
But that was as I was in transition and I was pushing minutes later. I did it with everything else - TENS, G&A and pethadine and it was sooooo much better. I could get up and about when I wanted, changed positions easily and had a bath and some time in the pool. I had just 6 hrs hard labour this time.
If I have anymore I'll be doing it the same!!
