Physical and cognitive development in the first two years

Summary

Physical and cognitive development proceed at a breathtaking pace in the first two years of life. Infants enter the world as competent individuals who actively explore the external world from the moment of birth. As their basic reflexes disappear, they begin to engage in intentional and purposeful behavior. Their ability to move, as in crawling and walking, and to manipulate objects extends their opportunities to learn about the physical environment. Responsive and supportive caregivers who work with infants and toddlers play a critical role in providing an optimal learning environment that takes into account infants' unique developmental needs. The next segment of the four-part series addresses the social and emotional development of infants and toddlers.
