I was fully expecting to have a csection. I heard twins usually did. When we did the birthing class, both of them were feet down indicating that it would most likely be a c section. I remember hearing instructions for breathing and pushing, but I didn't worry about it too much. Those instructions wouldn't apply to me

as the due date got really close, darn it, they both managed to turn themselves around. After my water broke and I was at the hospital, I'm frantically asking my husband to google how to breathe during labor. I had forgotten to look it up earlier

Both were delivered vaginally.
You never know with twin pregnancies.
