To start things off, I just finished a FANTASTIC book called "Our Babies, Ourselves: How Biology and Culture Shape the Way We Parent" by Meredith Small. It's an anthropological look at how people approach parenting with their babies across cultures (the field is actually called ethnopediatrics!), and Small's main point is that we tend to approach parenting from the perspective of assuming that our cultural norms are actually what's best for babies, when in fact that's not always the case. She looks at feeding, sleeping, crying, and level of interaction across a number of cultures. It's an easy read and I HIGHLY recommend it.
If anyone's read it, I'd love to hear your thoughts!
