I wrote my response before reading the others. I saw some notes about emotional maturity. Children raised in safe, mature, and loving homes often don't need much preperation to raise children because it was modeled to them growing up.

I would point to all the trauma caused by fiat wars, media manipulation, addiction, and poverty passed down through the generations.

Now it takes 30+ to unfuck your soul to avoid passing it on to your kids.

Just speaking from my own experience here 😂
