By what measure? Cultural relevance or actual legal authority?
> No one actually knows how to raise children.
We have a much better idea now about how to meet the developmental needs of children than ever before, I think almost anyone would argue. We have studies on the outcomes of things like corporal punishment. We have the ACE study and it’s effects. So many other foundational developmental science has been done in the last 30 years.
> I think it's better to let parents do their best. This leaves us with some children who were over-disciplined and some who were under-disciplined and this is a better outcome than everyone being screwed up in the same way.
I certainly won’t argue against that but I would argue that having people have at least a cursory education on child rearing might be something that would help. As a survivor of abuse it’s very difficult to allow for the idea that nothing further could be done for kids in similar positions.
