c.1200, "the young of a goat," from a Scandinavian source (cf. Old Norse kið "young goat"), from Proto-Germanic *kiðjom (cf. Old High German kizzi, German kitze, Danish and Swedish kid). Extended meaning of "child" first recorded as slang 1590s, established in informal usage by 1840s. Applied to skillful young thieves and pugilists since at least 1812. Kid stuff "something easy" is from 1913 (The phrase was in use about that time in reference to vaudeville acts or advertisements featuring children, and to children-oriented features in newspapers).
