Young creature: I’m holding her little angels! (8)
I believe the answer is:
cherubim
'little angels' is the definition.
(plural of cherub)
'young creature i'm holding her' is the wordplay.
'young creature' becomes 'cub' (I've seen this before).
'holding' is an insertion indicator.
'cub'+'im'='cubim'
'cubim' going around 'her' is 'CHERUBIM'.
(Other definitions for cherubim that I've seen before include "Angel" , "Angels depicted as winged children" , "Angels, usually portrayed as winged children" , "Angelic beings grouped with seraphim" , "Angelic Children, often winged" .)
