I think better than the nuclear family is the extended family and a support network and friends who help out. I moved to NYC to help out my aunt and uncle with her twins and it was quite a wonderful experience. Sure there were times it felt like drudgery. It's also quite a good birth control. There are quite enough children in the world, go help someone else out. Why do they have to be yours? The responsibility of your children is that you're the last line, when nobody else cares. I think the best and simple way to be a good parent is to be present. From there all else unfolds.
But beyond my little quibble that it's more the support network, there were many interesting insights that I won't give away in the first chapter. I enjoyed it.
