Hi all,
I'm currently 36 + 4 with my third, had a midwife appointment today and baby is 3/5 engaged, which is great, but unfortunately his little hand is up by his head.
My midwife briefly mentioned how it's called compound presentation and that might mean additional trauma down below for me when I give birth but that's about it.
Anyway, since coming home from the appointment I've googled it and, well, I've terrified myself!
I'm all set for a home birth, but this compound presentation seems to increase the risk of shoulder dystocia and the umbilical cord getting trapped around the neck etc, not to mention it's highly likely I'll end up with a third degree tear!! 
Does anyone have any experience with this compound presentation??
