The children produce a publication (5)
I believe the answer is:
issue
I believe this 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 publication' is the third definition.
(I know that publication can be written as issue)
(Other definitions for issue that I've seen before include "Contentious subject" , "Question in dispute to be settled" , "Send out or distribute for use" , "Important topic for offspring" , "Sprogs" .)
