No one is an expert on parenthood.

Good parenting is only doing better than your parents.

>Good parenting is only doing better than your parents.

Also making the mistakes that your parents did not make.

Did anyone say anything about being an expert?

But even if someone had, I will happily propose that every parent who cares about being a parent is an expert on parenting.

But they are certainly closer to it than childless people.

Perhaps even worse. I'm over simplifying: but at least some childless people know it's a lot of work and sacrifice to be a good parent, hence they opted out. On the other hand for the clueless ones, they thought of a child as something akin to having a toy - all fun and no work, only to realizes later that they are dealing with a full fledged individual.

Hence they delegate it to the experts: daycare, school etc. /s
