Kids can be a problem (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
issue
I believe this clue is a double definition.
'kids' is the first definition.
(legal term for a person's children)
'a problem' is the second definition.
(thesaurus)
'can be' acts as a link.
(Other definitions for issue that I've seen before include "Hot topic; outcome" , "Circulate, distribute or equip with" , "Number (of periodical)" , "Progeny of, send out" , "Topic; give out" .)
