Two days ago I had a natural water birth at a Hospital. My husband and doula were with me and the attending on duty was an OBGYN from my practice. I could've specified a mid-wife, but all the doctors at my practice were on board with my birth plan and the one that delivered my baby has performed a cyst removal surgery on me before so I was really comfortable with her. I think it helped that my hospital is also known as being a big proponent of natural birth, which is sometimes rare in the US.
