Go to Motherwear's Breastfeeding Blog for a fun excerpt from Breastfeeding Made Simple: Seven Natural Laws for Nursing Mothers, by Kathleen Kendall-Tackett and Nancy Mohrbacher.

It explains the four different types of mammals, and why our breast milk is designed to be so low (comparatively) in protein and fat.

(To break the suspense, it's because human babies were designed to be carried around and feed all day long!)

Tanya says it might be geeky that she finds comparisons to other animals so fascinating. I'm too much of a geek to say whether it is or isn't, but I'll share in the fascination.
