If it mentioned cesareans, it would be near perfect.
It's not a perfect book, but it's a great foundation. And the illustration style, where it can be very detailed in some parts of images, and quite abstract in others, works very well for the topic. It's a nice contrast to the weirdly cartoony images and metaphors of "Where Did I Come From?" There are no descriptions of how anything feels, just a factual recounting of events.
