Why isn't my child as clever as me? (2013)

There's a correlation between rich/poor/smart/dumb and parenting effectiveness but there's so much noise that nobody's surprised when a rich smart couple has a deadbeat kid or vise versa.
Just being smart won't save her if she's a crap parent but people are resilient enough that unless she's really good or really bad it probably won't make a huge difference a decade down the road.
Intelligence is forged in the fires of necessity. When a child must struggle against reality to feel safe, they must learn how to predict the future accurately, which will create the learning context for developing intelligence.
A child who has plenty of family support to get things done, succeed in school, etc, but who is surrounded by social pressures to appear to be a certain kind of person will instead get good at appearing to be a certain kind of person.
The kid is not in control, the mother is. It is a job of the person in control, to adapt and change the behavior, in order to change outcome "every session ended in tears and dejection".
Not that this point contradicts anything in the article. You can still wish your children had inherited your cultural posture.
"All the other milestones found her trailing behind her peers: potty-training, dressing herself, identifying colors."
These seem less like specific intellectual milestones than general developmental ones.
I think it's the integrated picture her daughter presents that she finds challenging, not solely her intellectual milestone schedule.
There are many kinds of intelligence!
