If 2 parents make a good kid then maybe 3 parents make a better kid.
It used to be people lived near their extended family. Lots of parents there.
Be aware that this "nuclear family" is a recent and historically strange thing. It has not been tested in the long term. In all likelihood it's bad for us.
Extended family is definitely better for raising kids. The problem is nuclear family is better for chasing good jobs and making money (likely far away from extended family).
As the saying goes, you can serve Mammon/wealth, or god/your community of origin, but not both.

Maybe in very early human history, but research suggests that humans had already moved beyond Africa 180,000 years ago. For all intents and purposes, people have always left their family in search of a better life.
What is recent is the practical ability to keep in touch with extended family even when afar. It is possible that hinders the creation of supportive communities to stand in for where biological families are missing.
