This is a set category. It should only contain pages that are children or lists of children, as well as subcategories containing those things (themselves set categories). Topics about children in general should be placed in Category:Childhood or one of its subcategories. Categories related to only an individual child should not be in this category.

Wikimedia Commons has media related to Children.

This category contains articles or subcategories primarily about individuals who became notable as children, either before age 18 or before the age of adulthood or majority in their respective societies. Additionally, some articles or subcategories are about people who became notable as adults, but whose childhood was retroactively notable or relevant, such as Army brats.

As noted, this category is for articles about individuals; all other articles and categories belong in Category:Childhood.
