These are really interesting questions. I haven't got any children, but I'll share some of my friends' and family's experiences
In the UK, a home birth is not recommended for your first child. In fact, I don't think they'll let you have one (unless you go into labour quickly and it's too dangerous to move you!) The reason for this is that noone knows if you'll have a difficult birth or not. However, if you have already had one child with no complications, you will be supported in having a home birth, and will be assigned a midwife who can come to your house.
Remember that, years ago (and still in some countries!), many women would die in childbirth, and a high number of children would die in infancy. So a natural birth does carry some risks.
I have an aunt who insisted on a natural birth. After a few hours she was begging for the drugs

In my family, we tend to have sick labours, usually lasting 24-48 hours and ending with a caesarian! Some women are so traumatised by this that they find it hard to bond with the baby. However, I have friends who had a relatively fast labour (5 hours max) and didn't need the drugs or gas - in one case it was all over before the midwife arrived!
Maybe you could speak to your family and see whether they have a tendancy to have complications during labour?
In some areas there are birthing centres, where you can have a relatively natural birth, but there are medical facilities if you need them. They can offer natural pain relief, quiet births and water births. Maybe this could be an option?
Hope that's some help

Are you expecting twins? Let us all know how it's going!
