Crikey this has been an interesting morning's debate! Castanet, not sure if you are still reading this but if you are I'd really like to add my thoughts: Firstly, it does seem to me that you are equating having a baby with having a major operation. Yes, there's no doubt if I was having a heart transplant I'd rather be in a major London hospital than some rural outfit, stands to reason, but what I think lots of Mums are trying to get across is that having a baby is not a medical procedure. It really isn't. And it's not about the mother's wellbeing over the baby's either. You seem to have understood that most MNers who have home births are doing it because they are too damn lazy to get out of their own beds and would rather put their baby's life in danger than travel into hospital. It's not this simple, of course. It's not about shunning medical science either. You don't need much medical science to squeeze a baby out in most births - and if forceps and ventouses are the best that medical science has to offer in 2007 then God help us!
Birthing a baby is an incredible, life changing experience which will stay with you forever. How you deal with it and cope with it affects your baby 100%. I don't wish to sound patronising but it's impossible to explain until you have birthed a bay yourself. Your feelings, reactions and behaviour as a mother in the early days are so integral to how you bond with your baby and therefore how your baby feels, that it seems perfectly obvious to me that if you have a terrible time and are totally freaked out by the whole thing, then this will negatively impact on your baby.
Pardon me for saying so, but I think your opinions re hospitals are somewhat naive. Yes you can have a dangerous situation at home, but the same is true in hospital and bless you for thinking you get immediate medical attention in a hospital labour ward! If you are in the Portland then maybe you do but elsewhere I'm afraid you are just as likely to be left in a corridor screaming blue murder - even more so in an all singing all dancing London hospital than in a smaller place. having said all of this I believe you are having twins which is often a different situation entirely.
For the record I have not had a homebirth - it didn't occur to me at the time as I didn't really know enough about it, but as someone who has given birth I feel like I am qualified to defend the rights of those who wish this experience. I was lucky enough to have a fabulous birth in a major London hospital last year with the midwife who cared for me throughout my pregnancy (all NHS, numbers came up in the postcode lottery!) but I came home as soon as possible because the care you receive in hospital is truly substandard, both for you and your baby and if you are lucky enough to have a supportive partner and/or family you are way better at home.
Good luck with your pregnancy and birth...I hope you get the birth you want, the birth that's best for you and your babies because really that's just what all of us want.
