Pediatrics:

Pediatrics is the branch of medicine that involves the medical care of infants, children, and adolescents. The American Academy of Pediatrics recommends people seek pediatric care through the age of 21. In the United Kingdom, pediatrics covers patients until age 18. Worldwide age limits of pediatrics have been trending up year over year. A medical doctor who specializes in this area is known as a pediatrician, or paediatrician.
