i had an epidural for no 1 - I had v. high blood pressure, odema and I was 3 days overdue. They decided to induce as contractions were "unco-ordinated". However, birth itself was traumatic - ventouse (sp?), baby in distress, no urge to push, terrified.
Part of the problem was that I was left alone, without midwife, for ages. When babies heart rate began to dip below 70, I had DH go call a midwife. :( This was in St Peters, Chertsey - one of the subjects of the Kennedy commission, and still not highly regarded. During the same week, a baby died due to negligence at the unit.
No 2 and No 3 were delivered in a different hospital. My community midwife delivered No 2, and the student midwife at that delivery delivered No 3. :)
In both No 2&3 I had gas and air only. It hurt, but my midwife was attentive and kind and calm and reassuring. The most effective statement she made was "hatti, you are coping well at 5cm, the pain will not get any worse, they will just get closer together. But if you need more, just ask, but I think you can do this with just G&A" - which was true. As it was, with both No 2&3 I went from 5cm to 10cm in about 25 minutes. probably as midwife encouraged me to get off the bed and move around.
I think our expectattions are so unrealistic with first babies, and the pain is shocking. All my NCT classes had said it was like bad period pains...yeah, right 
But with subsequent babies, you know you can do it, you can focus on the outcome.
Midwives make all the difference.
WIth No 3, midwife was lovely, but we caught her offguard...she rushed in all flustered as I was mooing about pushing, saying "oh bloody hell, I knew you were going to be quick, but at least let me get my bloomin' gloves on!"
We even managed to have a laugh about the lady next door, who was 10 hours in, with "whale song and candles" was not going to get off the bed. MW said she was going to march right in there and tell Mrs Whalesong that I delivered in less than 2 hours because I was on my feet.
