How do you know how to parent?

Just wondering. Did Info get passed generationally? Books? Friends? Instagram reels? Pediatrician handouts?

I feel like I’ve pulled a little from here and there but don’t know if I’m getting things right.

Sleep for example (I have a 5 month old). Sleep trainer says one thing, book about nurtured parenting says opposite. Not sure which advice to follow.

My husband says if there’s differing opinions then it must not be that important or very individual, which I’m inclined to agree with.
