Monoamniotic twins used to ALL be born at home vaginally. .... The Dionne quints were five, identical, same sack for 5 and were born at home.
I think Elizabeth Noble's book Having Twins is pretty good. It has a lot of information about homebirth. Most everything is just scare tactics. I also think the aboutpregnancy guide had a homebirth with twins, but I can't remember if they were monoamniotic.
Hopefully a midwife will pop in, but I think that it's fairly easy to determine if a baby is having problems....especially if the mother is in tune with her body and her babies.
OBs barely know how to do breech birth these days. I wouldn't put too much stock in what they say about twins. Monoamniotic or not.
Almost all babies are safest being born at home.
