Put off baby's toy (6)
I believe the answer is:
rattle
I believe this is a double definition.
'put off' is the first definition.
(thesaurus)
'baby's toy' is the second definition.
(I've seen this before)
(Other definitions for rattle that I've seen before include "Child's toy or kind of snake" , "Trivial talk" , "Baby's toy - conductor" , "Make nervous; child's toy" , "Shake - baby's toy" .)
