Children's edition (5)

I believe the answer is:

issue

I believe this is a double definition.

'children's' is the first definition.
(issue can mean someone's offspring)

'edition' is the second definition.
(eg edition of a magazine)

(Other definitions for issue that I've seen before include "Matter, point" , "Matter of contention" , "Send out or distribute for use" , "Matter for discussion" , "One of a series published periodically" .)

I've seen this clue in The Daily Express, The Mirror, The Times and The Globe and Mail.
