Early Brain Development

In the first few years of life, more than 1 million new neural connections are formed every second.

Explore our resources about key stages of early brain development.

From birth to age three, the brain experiences rapid, transformative growth that shapes lifelong learning, behavior, and mental health. 

Understanding the phases of brain development can help caregivers make a lasting impact during these critical years.

During the first three years of life, the brain triples in volume.

The neuroplasticity of early childhood makes young children incredibly vulnerable, but also incredibly resilient and responsive to positive intervention.
