Early childhood development is an incredible time of physical, cognitive, and social and emotional development.

Studies show that after the first 2000 days—roughly 5 ½ years--a child’s brain is already 90% developed.

A growing body of science shows that early childhood influences, positive or negative, has the potential to impact lifelong health and social outcomes. The Center for the Developing Child at Harvard University, has posted a three-part series video series, entitled, "Three Core Concepts in Early Development" from the Center and the National Scientific Council on the Developing Child, to highlight the science behind early childhood development.

Three Core Concepts in Early Development

1. Experiences Build Brain Architecture

2. Serve & Return Interaction Shapes Brain Circuitry

3. Toxic Stress Derails Healthy Development

To illustrate how crucial caregiver experiences and interactions are in the development of young children, the following video shows how the prolonged lack of attention impacts infant’s socialization. The video, “Still Face Experiment,” features Dr. Edward Tronick from the University of Massachusetts.
