- Young children's brains undergo a five-to-seven integration shift enabling impulse control and delayed gratification, so they are built for play not formal work.
- Forcing outcome-driven tasks before integration creates defense around learning and can turn children against schooling.

- Attachment's deepest purpose is to keep a child's heart soft so they can feel vulnerable emotion and grow.
- Emotional development scaffolds prefrontal cortex architecture, so shutting feelings down arrests development and maturity.
