You commented on my comment, using your experience to support a claim that societal pressure about who parents (and how) is biologically driven.

I countered with my own experience that it is not.

Ancedata all around.

I'm glad your system works for your family. Similarly, I'm glad ours works for our family. But from both stories we can see that what you claim as a biological fact is not so clear.
