Novice carries her lovely child (6)
I believe the answer is:
cherub
'lovely child' is the definition.
(I've seen this before)
'novice carries her' is the wordplay.
'novice' becomes 'cub' (cub is a kind of novice).
'carries' is an insertion indicator.
'cub' placed around 'her' is 'CHERUB'.
(Other definitions for cherub that I've seen before include "Sweet innocent baby" , "A heavenly winged babe" , "High-ranking angel" , "Angelic baby" , "goody-goody?" .)
