Little child has item to play with (4)
I believe the answer is:
mite
'little child' is the definition.
'item to play with' is the wordplay.
'to play with' indicates an anagram (I've seen 'played with' mean this (I've seen this in other clues)).
'item' with letters rearranged gives 'MITE'.
'has' is the link.
(Other definitions for mite that I've seen before include "Tiny arachnid, person or amount of money" , "The widow's small offering" , "The widow's small donation" , "Tiny contribution, child" , "Minute arachnid" .)
