Put out again about children (7)
I believe the answer is:
reissue
'put out again' is the definition.
('issue' can be a synonym for 'put out' so perhaps 'reissue' is OK for 'put out again')
'about children' is the wordplay.
'about' becomes 're' (regarding**).
'children' becomes 'issue' (I've seen this before).
're'+'issue'='REISSUE'
(Other definitions for reissue that I've seen before include "Send out again" , "New edition of book" , "Do 11 Down again" , "get book brought out again" , "Put out old material" .)
