You write, “Parenting makes us human.” What anthropologists such as Sarah Blaffer Hrdy and others say is that it was female cooperative breeding, or alloparenting— the “sharing and caring derived from the pooled energy” of a network of “grandparents, aunts, uncles, siblings, distantly related kin, and non-kin” — that actually shaped human evolution. But clearly it comes down to children and the raising of children. Today’s parents see raising children as their sole responsibility, which not only hurts them but their kids as well. We need to go back to a collaborative parenting model.
