• Early relationships have permanent effects on brain development, health, and later mental health.
• Social-emotional and physical health are inseparable in the very early years.
• Responsive caregiving can mediate the effects of some chronic health conditions, e.g., prematurity, poverty.
• Social and emotional development is strongly linked to success in school (and beyond).
• Intervention can be effective; children and adults can recover.
