Sweet little toy (6)
I believe the answer is:
trifle
I believe this clue is a triple definition!
'sweet' is the first definition.
(I know that trifle is a type of sweet)
'little' is the second definition.
(thesaurus)
'toy' is the third definition.
(both can mean to play with)
(Other definitions for trifle that I've seen before include "A mere dessert?" , "Thing of little value or importance" , "Dessert - toy" , "A small portion" , "Dessert - something unimportant" .)
