Control over emotions and body
Self-understanding
Empathy

A child whose upstairs brain is properly functioning will

As you might expect, a person’s brain works best when the
upstairs and downstairs are integrated with each other. So a
parent’s goal should be to help build and reinforce the
metaphorical stairway that connects the child’s upper and lower
brain so that the two can work as a team. When a fully functioning
staircase is in place, the upper and lower parts of the brain are
vertically integrated. That means that the upstairs can monitor the
actions of the downstairs and help calm the strong reactions,
