| Pediatrics (also spelled paediatrics or pædiatrics) is the branch of medicine that deals with the medical care of infants and children. The word pediatrics is derived from two Greek words paidos which means little boy and iatros which means doctor. Most pediatricians
are members of a national body, such as the American Academy of Pediatrics, the Canadian
Paediatric Society, the British Association of Paediatric Surgeons, or the Indian Academy of Pediatrics.
One of the major challenges facing pediatricians is that the range of
body sizes (and weights) that they face in pediatrics is much greater than in adult medicine. For example, a preterm neonate can be less than 2kg in weight while an obese adolescent may be larger than the typical adult.
Childhood is the period of greatest growth, development and maturation of the various organ systems in the body. Years of
training and experience (above and beyond basic medical training) goes into recognizing the difference between normal variants
and what is actually pathological.
Another major difference between pediatrics and adult medicine is that children are minors and, in most jurisdictions, cannot make decisions for themselves. The issue of guardianship, legal responsibility and informed consent must always be considered
in every pediatric procedure. In a sense, pediatricians often have to treat the parents (and sometimes, the family), not just the
child.
Abraham Jacobi is considered the father of pediatrics.
