Children's publication (5)
I believe the answer is:
issue
I believe this is a double definition.
'children's' is the first definition.
(thesaurus)
'publication' is the second definition.
(issue is a kind of publication)
(Other definitions for issue that I've seen before include "hot potato?" , "Children; put out" , "Put out; topic for discussion" , "Result, outcome; topic" , "Matter for discussion" .)
