Pediatrics is the branch of medicine concerned with the health of children from birth through adolescence. It aims to ensure the healthy growth and development of children as well as prevent, diagnose, and treat illnesses. The field has grown significantly throughout history as more emphasis has been placed on children's health, welfare programs have been established, medical science has advanced, and societies have changed in their view of protecting younger generations. Modern pediatric nursing focuses on advocacy, communication, education, and collaborative care for the child and family.
