Edition for children (5)
I believe the answer is:
I believe this clue is a double definition.
'edition' is the first definition.
(eg edition of a magazine)
'for children' is the second definition.
(issue can mean someone's offspring)
(Other definitions for issue that I've seen before include "Problem - child" , "The children to come forth" , "Important question" , "Point under discussion" , "Subject for discussion; dish out" .)
