Brains are built and grow through touch, talk, sight and sound in early childhood experiences. This experiential learning starts long before a child steps foot into kindergarten and, is strengthened through regular interaction and stimulation in the home and in quality early learning settings.
During the first five years, a child’s brain is at its most flexible, making this a critical period for learning and growth. Science tells us that children who face adversity in the first years of life, especially those in low-income households, are more at risk for experiencing damage to their brain architecture, which can lead to lifelong problems in learning, behavior, and physical and mental health. Prevention through high-quality early learning and care provide the support children need to build a foundation for a healthy and productive future. Waiting until kindergarten is too late—children who receive quality early education demonstrate greater cognitive and socio-emotional growth than children who do not. Consider the following:
- More than one million new neural connections are formed every second in the first few years of life. 
- 90% of a child’s brain physical volume develops as early as five years old. 
- The brain is most flexible and adaptable to learning during the earliest years of life. 
- Children who face greater adversity, like living in poverty, are at far greater risk for delays in their cognitive, language, or emotional development. 
- By age three, children with college-educated parents have vocabularies two to three times larger than children with parents who did not complete high school. 
- Children are already rehearsing how to produce language at seven months old. 
- Even as babies, children are learning the social skills that determine their future social capabilities. 
- A supportive learning environment reduces the risk of children experiencing developmental delays. 
- The brains of babies and young children require stable, caring, interactive relationships with adults in order for healthy brain development to take place.
