Children copy (5)
I believe the answer is:
issue
I believe this is a double definition.
'children' is the first definition.
(issue can mean someone's offspring)
'copy' is the second definition.
(thesaurus)
(Other definitions for issue that I've seen before include "One of a series published periodically" , "Argument" , "Give out; children" , "Emit" , "Offspring; publish" .)
