Well, let me add my experience.
dd was my first, born in a hospital. I was doing just fine with my TENS when I arrived. Almost straight away the young midwife took my TENS off me as she said it would interfere with the machines she was hooking me up on to monitor the baby's heartbeat and my contractions.
She then went out and I was left alone with dh.
My waters broke and the pain became more intense. She examined me and said I would probably be in this much pain, if not worse, for hours yet. That frightened and panicked me. She told me to have pethadine - even though it was highlighted in big bold letters by the doctor on my birth plan not to give me pethidine under any circumstances because of my state of mind. If it wasn't for dh insisting that they read this, they would have just gone ahead with that. They then changed my mind and decided that I should have an epidural.
They took all control away from me. They decided what I should have and when. They never reassured me or treated me as a human being, I was cattle to them. They even came in and told me when to push and how long for.
After dd was born I was taken down to the ward and put with a load of women who had not yet given birth, I was the only one with a baby. I was given no support and if I asked for anything they treated me roughly, like I was a major pain in the ass. I was eventually transferred to a midwife only unit but even that was a struggle.
With my second I decided to go for a home birth as I genuinely believed it to be safer for me and my child. I trusted my community midwife 100%. I got to make some decisions concerning my own health, I felt much more in control and relaxed.
I was able to have a natural labour without pain relief. There were no complications and it was lovely to be able to relax in my own home with midwifes who wouldn't abandon us and who didn't treat me like cattle. I believe the baby benefitted too because the whole experience was just so much more relaxing whereas with dd it was just awful, medical, panicky and she was born with the cord wrapped round her neck twice. The midwives even panicked and ended up covered in blood after hacking through the cord to get to her.
If I were to give advice, I would advise a midwife only unit or a home birth. I would never recommend a hospital birth because of the trauma to the mum and baby.
