Publication for children (5)
I believe the answer is:
issue
I believe this clue is a double definition.
'publication' is the first definition.
(I know that issue is a type of periodical)
'children?' is the second definition.
(issue can mean someone's offspring)
'for' acts as a link.
(Other definitions for issue that I've seen before include "that may be taken where there's disagreement?" , "Continent" , "Outflow or point of concern" , "Important problem" , "Important topic for debate" .)
