Innocent child (6)
I believe the answer is:
cherub
This clue is a double definition.
'innocent' is the first definition.
(I've seen this before)
'child' is the second definition.
(cherub is a kind of child)
(Other definitions for cherub that I've seen before include "Angelic baby" , "Baby angel" , "A heavenly winged child" , "High-ranking angel" , "Angel portrayed as a winged child" .)
