You get gas and air at home but not an epidural and not pethidine. They
can also give you syntometrine at home (this speeds up 3rd stage) if you
want it. And if things are going slow you can transfer to hospital,
changing your mind at any point and heading there if you just decide
home isn't the place you want to be after all.
Just consult with your gp and your midwife if you have one. I really don't like hospitals, that's why home birth was my decision in the first place. I feel safer at home
