The NHS is not exclusively to blame - we are in a medical-central culture where the majority of people feel safer in hospital. However, I had a home birth for my 2nd daughter and it was the best decision I ever made. If women could see a home birth for themselves, they may change their mind. Maybe they can bring the ideas into Antenatal classes?
It a sad fact that the majority of babies were born at home up until the 60's and then it all switched to obstetric care in the hospital setting. You are thought to be 'out of the norm' if you have a home birth now and I have had many different reactions about my choice to birth at home - good and bad. Most people say "wow, you're brave" - but its not about being brave!!
At the end of the the day, midwifery is about "women-centred care" which means that the mother's choice is at the centre of her care - and not everybody's personal choices are the same.
