If all of those well-meaning and loving parents from the article I linked previously quit the idiotic committees on how improve schools and went home to be with their kids, that would have a dramatically positive effect on the kids.
A mom who is folding laundry while the kids are pottering around with their toys at her feet is doing a million times more for their brain development than the mom sitting at the stupid committee.
I’m not saying this as a layperson but as somebody with an exotically long background in pedagogy and early childhood education. I grew up in a family of pedagogues and started reading books on early childhood development at six. Seriously, that’s what I did. The books were all samizdat because they were illegal in the USSR. I perceived these books that were typewritten, hidden in secret places, and passed from hands to hands by whispering adults as something extremely fascinating, so I devoured them.
Children need their parents to just be there. Not doing anything in particular, hanging out, shooting the breeze. That’s what develops children’s brains and not committees on diversity, “integrated schools” of after-hours school programs.
