(1) Why is it human? Men don't give birth. Before you say, well, they had to distinguish the species, think hard about what _that_ says.
(2) Notice that while there is a baby on the cover, there is no mother. Whoa. They _erased_ mom from the picture entirely. Spooky.
(3) While mom has been erased, the time lapsed drawing/diagram tells you exactly what position she is giving birth in. Take a good look -- it's almost certainly semi-sitting. (Either that, or lithotomy.)
Title does get points for saying labor and birth, not labor and delivery, hence it does actually describe work done by mom, rather than focussing primarily on the birth attendants activities (which would be delivery).
I think I'm going to get Robbie Davis-Floyd's book. She may be crazy, but it is increasingly difficult for me to think she's wrong.
