Pediatrics (also spelled paediatrics or pædiatrics ) is the branch of
medicine that involves the medical care of infants, children, adolescents, and
young adults. In the United Kingdom, paediatrics covers many of their youth
until the age of 18. The American Academy of Pediatrics recommends people seek
pediatric care through the age of 21, but some pediatric subspecialists
continue to care for adults up to 25. Worldwide age limits of pediatrics have
been trending upward year after year. A medical doctor who specializes in this
area is known as a pediatrician , or paediatrician.
