Interesting. And the parents also go though a kind of attachment Renaissance, learning to care once more, some saying they feel their life has changed. I wonder if after those 4 phases, we kinda forget how to be attached, and then we learn once more when we become parents.
It's also interesting that the child mainly attaches to one figure. I wonder how or if that relates to monogamy, whether we're wired to always care more about one person.
And I wonder what the Buddhists would say about this, seeing as they preach non-attachment! Which I consider, correctly it seems from this post, to be unnatural, and even impossible.
