Another publication regarding children (7)
I believe the answer is:
reissue
'another publication' is the definition.
'reissue' can be an answer for 'publication' (reissue is a kind of publication). I'm unsure of the 'another' bit.
'regarding children' is the wordplay.
'regarding' becomes 're' (re can mean regarding, concerning).
'children' becomes 'issue' (issue can mean someone's offspring).
're'+'issue'='REISSUE'
Can you help me to learn more?
(Other definitions for reissue that I've seen before include "Send out again" , "get book brought out again" , "Put out old material" , "New edition of book" , "publication (not a first!)" .)
