The children produce a magazine (5)
I believe the answer is:
issue
This clue is a triple definition!
'the children' is the first definition.
(issue can mean someone's offspring)
'produce' is the second definition.
(I've seen this before)
'a magazine' is the third definition.
(I've seen this in another clue)
(Other definitions for issue that I've seen before include "Distribute for sale/use" , "Topic (to be addressed)" , "Contentious subject" , "Matter for discussion" , "one's children?" .)
