I think people really forget the “it takes a village” lesson andremebrer that no kid is raised only by their mom and dad.
There was a video about this posted a bit ago. The speaker said basicly this same thing. After the age of 7, the environment that your kid is placed into, and the other people they are around, has for more influence on them that the parents have.
You do your best for the first 7 years, and then you do your best to find the right environment for them for the rest of their lives.
