Infants begin a lifelong process in which their natural curiosity and experimentation produce learning. Children are guided in making sense of their world. As their natural wills are nourished and nurtured, a self-actualized, independent being develops capable of living harmoniously within the world. The learning is developmental in nature; that is, knowledge is based on previous learning and continues to expand and grow with the child. The teacher is the nurturer and facilitator within the child care center. This person prepares the environment to challenge and stimulate the child at their own level of development.
