Children may be a contentious point (5)

I believe the answer is:

issue

I believe this is a double definition.

'children' is the first definition.
(thesaurus)

'a contentious point' is the second definition.
(I've seen this before)

'may be' is the link.

(Other definitions for issue that I've seen before include "Put out; result" , "Send out or distribute for use" , "Shares" , "Major topic for debate" , "Important topic for offspring" .)

I've seen this clue in The Telegraph.
