Ask HN: Any good collaboratively built documentation on good parenting?

Lastly, I wonder whether there is a good collaborative resource providing consensus-based good parenting practises and guidelines, from a general point of view: Which, of course, would include, techniques, methodologies or guidelines depending on the age, type, culture or context where children grow up.

Am I requesting for a kind of an impossible-to-find asset?

I'd appreciate your thoughts on this.
