Childcare, otherwise known as day care, is the care and supervision of a child or multiple children at a time, whose ages range from two weeks of age to 18 years. Although most parents spend a significant amount of time caring for their child(ren), childcare typically refers to the care provided by caregivers that are not the child's parents. Childcare is a broad topic that covers a wide spectrum of professionals, institutions, contexts, activities, and social and cultural conventions. Early childcare is an important and often overlooked component of child development.

Child development involves the biological, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence.
