The phrase has been used since the 1300s. The phrase has changed since the original “child’s game.”
The present idiom was used by Geoffrey Chaucer (c. 1343 – 25 October 1400) in The Merchant’s Tale:
“It is no child’s play to take a wife.”
It is easy to assume that a game that is suitable for children to play will be simple for people of superior intellect. Thus, it makes it sound as if the person using the expression is smarter than someone who could not master the skill. In some instances, it is used by someone to make others feel inferior.
