Contentious topic for children (5)

I believe the answer is:

issue

I believe this is a double definition.

'contentious topic' is the first definition.
(as in a controversial issue)

'children' is the second definition.
(issue can mean someone's offspring)

'for' is the link.

(Other definitions for issue that I've seen before include "Important topic for debate" , "Difficulty" , "Spring - children - publication" , "Contentious subject" , "one's children?" .)

I've seen this clue in The Telegraph.
