I'm not disagreeing with what you've linked said but it's pretty well documented that there are negative events that can lead to long term impacts on children. The letter you linked seems to glance over parents who are abusive, whether that is verbal, physical, or neglectful.

For those that want to dive in a little bit these are Adverse Childhood Experiences (ACE). It's not an end all be all chance that you'll develop something with a long term impact but the more you experience the more likely you are to do so.

You can do everything right and your kid will still have an ACE.

Lil Timmy falls down a well, or has a really handsy neighbour, or has to see someone get hit by a car.

Like, obviously, don't beat your kids, but you don't need to be superlative parent, esp. since a great deal of their education and raising will happen, essentially, in someone elses workplace (i.e. school).
