Children's magazine? (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)
'magazine?' is the second definition.
(I've seen this before)
(Other definitions for issue that I've seen before include "Pour forth" , "Result - children" , "Distribute for sale/use" , "Produce" , "important point" .)
