Pediatrics (also called pediediatrics or pædiatrics) is a medical branch that includes medical care for infants, children, and adolescents. The American Academy of Pediatrics recommends that people be in foster care up to the age of 21 (though usually only children should be under child care). The doctor who works in this area is known as the pediatrician, or pediatrician. The name children and their identity means "baby healer"; they come from two Greek words: παá¿–ς (pais "child") and á¼°ατρÏŒς (iatros "physician, healer"). Pediatricians work in hospitals, especially those under their care (e.g. neonatology), and external physicians who work outside.
