Before my DH retired as a captain of a major airline, I told him that if a pregnant woman started labor, when he paged for a doctor or a nurse, he was to tell the doc to standby, because My Wife, the OB Nurse, will tell you what she wants you to do. He looked at me for just a minute, and then said, "you're serious?" As a heartbeat, I replied, because if that guy is a shrink, a dermatologist, or a large number of other kinds I could name, I can guarantee you I've done this more, and more recently! An OB, maybe a family practice doc, or a vet, yeah, they could be helpful.
I'm guessing the others wouldn't want to be part of it anyway.
