As I’ve been searching for the same functionality for too long now, I’ve written one on my own.

is_child( “ParentCategory” )
is_child( 10 )
is_child( “a-nice-slug” )

Works for categories, posts and pages as well. As for posts, it checks all of a posts categories and all of their parents. Recursively. Or not, if you don’t want it to.

Check it out at

If you got any ideas, hints, helps or bugs, please leave your feedback.

Since I haven’t found a plugin yet which has is_child-functionality even for categories, postings as well as for pages, I gave up on searching and wrote one for myself.

Works with IDs, titles and slugs as search-term.
