A pediatrician is a medical doctor who specializes in this area and is responsible for managing the physical, mental, and emotional well-being of children at every stage of development, in both sickness and health. They provide a wide range of services, including preventive health maintenance, medical care for acutely or chronically ill children, and coordination of care for children after hospital discharge
. Pediatricians typically focus on individuals from birth to about age 21, although the age limits for pediatric care can vary by country and region
