A pediatrician is a medical doctor who specializes in the care of infants, children, and adolescents. They are trained to diagnose, treat, and prevent illnesses, injuries, and developmental issues in children.

Pediatricians typically work in private practices, clinics, hospitals, and other healthcare settings. They provide a range of services, including routine check-ups, vaccinations, and treatment for illnesses such as colds, flu, and infections. They also monitor children's growth and development, provide advice on nutrition and safety, and help parents manage behavioral and developmental issues.

To become a pediatrician, one must complete a medical degree program followed by a residency in pediatrics. After completing their training, pediatricians may choose to specialize in a particular area, such as neonatology or adolescent medicine.
