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.
In terms of long-term parenting philosophies, though, I'd strongly suggest reading Selfish Reasons to Have More Kids by Bryan Caplan: https://www.amazon.com/dp/B004OA64Q6/
It's a book length treatment of the fact that twin studies have demonstrated extremely convincingly that as long as you meet a pretty low bar for decent parenting (you aren't such an obviously bad parent that you would get rejected by adoption agencies) the impact of your parenting on your kids' lives is minimal at best. You won't make them smarter, you won't change their personality to be more adventurous or cautious, you won't succeed in molding them with all the life lessons you've learned, and you won't put them on a path to happiness (or unhappiness) when they grow up.
This may sound somewhat bleak if you're hoping to tiger-mom your children to Harvard. But it's also freeing--you can stop worrying, enjoy the ride more, and maybe most importantly, give your kids a fun childhood they'll look back on with pleasure.
