What's TRP's thoughts on having kids?

It's well established that a child who grows up with both a monogamous mother and father is better off developmentally than a child with separated parents. However, one of the largest red pill staples is to not get married. Obviously marriage is not a requirement for raising a family, but I personally have never met an unmarried couple who had children together, who were in a long term relationship and who were mutually content with staying unmarried. Not that it doesn't happen, but it must be exceptionally rare.

So what's someone to do who wants kids? It seems like convincing a girl to settle down and have kids sans marriage is nearly impossible; girls have been conditioned to desire marriage since they were children and most of them surely wouldn't settle for less.

Essentially, how do you get the nuclear family experience without legal marriage?
