I think it's very hard for pregnant women to make choices, because they get mixed messages. There is a "normal birth" movement, led by midwives, and supported by NCT, which argues that birth is a normal physiological experience and women should be helped and supported to give birth without drugs, and with minimal intervention, on the basis that that is what our bodies are designed to do.
Then there's the view taken by many obstetricians, which is that birth is dangerous, and that the most important thing is to get both the mother and the baby out alive. And that if that entails interventions, then so be it.
I don't see how women are supposed to be able to make intelligent decisions given that difference in opinion. They might go in, thinking, "I'll try for a nice positive experience and have a normal birth" only to discover that the midwife never looks at your birth plan, you're left lying on your back for hours unattended, and that if you then decide you need pain relief it just shows what a silly little woman you were for imagining you could cope without.
I just think there has to be a better way. Is it so hard to have a situation where women are properly looked after in labour, by supportive, kind midwives? That if you are capable of, managing without drugs, and that's what you want to do, you'll be supported? But if you want pain relief, you'll be given it straightaway and you won't be laughed at or sneered at? That if an intervention is needed, the people looking after you will explain why it's needed and what your options are, and the risks involved? Why do women have to be made to feel guilty all the time?
