The development of children begins at birth and continues throughout childhood. The early years of a child’s life are crucial to his or her overall development. Therefore, it is important to ensure that children are exposed to a wide variety of experiences during these years in order to promote optimal development. A child’s development is affected by many factors, including the quality of care he or she receives from parents, siblings, and other caregivers. It is also affected by the environment in which a child lives, the amount of stimulation and opportunities for learning, the nutrition he or she receives, and the physical health of a child.
