Modernity has upended this connection. Now having kids is basically a hobby that's almost guaranteed to make you poorer.
Point being that 'parenting' has become unnatural because the cyclical environment of 'do what your parents do' has been lost. Consequently many parents are clueless when it comes to raising their own children. It's become an intentional process they need to think about, and few of them know what to do. The default is being overly paranoid, because the necessity to learn skills to support the family isn't strong enough to override the parents paranoia.
My wife and I were letting our kids chop vegetables at age two. Many parents are so dumb they won't even let their kids do this until adolescence.
