Pediatrics is the branch of medicine that focuses on the health and medical care of infants, children, and adolescents from birth up to 18 years of age. It involves the prevention, diagnosis, and treatment of a wide range of childhood illnesses, from minor health problems to serious diseases. Pediatricians not only monitor physical health but also support emotional and developmental well-being, working closely with families to ensure healthy growth and development. This field requires a compassionate and comprehensive approach, as children have unique medical needs that differ from adults.
