Pediatric is the adjective form used to describe anything related to children, including their care, treatment, or diseases. It’s important to note that the noun form of this term is pediatrics, which can be used in both singular and plural contexts, but always retains the plural spelling.

A medical professional who specializes in the care of children is called a pediatrician. It’s worth mentioning that outside of the United States, the original British spelling is paediatric, paediatrics, and paediatrician.

In some cases within the United States, organizations or individuals may choose to use the British spelling, especially if they want to associate themselves with the historical or formal usage of the term.
