Butterpuff - I didn't want an epidural with DS (wanted a home water birth in fact!) but the labour was long and painful - due to him being back to back - and I got to the point where I felt totally out of control and couldn't cope with the pain any longer. I started begging for an epidural, and even though they said I was 8cm and didn't have long to go, I wouldn't take no for an answer!
I have to say, it was the best thing for me. I instantly felt calm and relaxed and because I was fairly close to delivery I could still feel the contractions as pressure, but they no longer hurt. I actually enjoyed the pushing stage, it lasted about 30 mins and I wasn't in pain at all.
I totally understand why people want to avoid epidurals, but for me at that stage, it was a really positive thing.
As for DD's birth, it couldn't have been more different! She wasn't back to back and arrived very quickly after my waters broke, so fast that I was still at home and was completely alone - DH had gone to take DS to his mum's, still thinking I had hours to go, and the MW didn't get there in time. She was born in the hall and I then called 999, although luckily she was totally fine. So that's why I had no pain relief, although the whole thing was so much less painful than DS's birth that I didn't really need it anyway.
So now I'm wondering how labour no 3 is going to go!!
