Children begin learning at birth. Every interaction that young children have with a caregiver adds to their experiences, which in turn influences the rapid brain development that occurs in the first few years of life and lays the framework for success throughout life. While it sometimes might seem like infants just eat, sleep, and need diaper changes, they are also taking in the world around them and responding to caregivers’ voices and facial expressions. After parents, teachers have the most significant role in harnessing children’s opportunities for development that arise in the early years. As such, the ability of families to access child care programs staffed by highly skilled and experienced teachers can have a major impact on children’s cognitive development.
