As seen above, paediatrics is a branch of medicine that deals primarily with the health and illnesses of children. As a matter of fact, the word paediatrics was formed in 1880, as a combination of the Greek word paid-, stem of pais "child" or pedo- plus -iatrics which comes from the from Greek word iatrikos "healing," from iatros "physician, healer," related to iatreuo "treat medically," from iaomai "to cure," from iaino "heat, warm, cheer" which means healing or medical treatment. When put together, the words form the word paediatrics which we commonly find today in hospitals referring to the branch of medicine dedicated specially to the little ones, also known as the ones of the next generation.
