A little drink for child (3)
I believe the answer is:
tot
I believe this is a double definition.
'a little drink' is the first definition.
(tot can mean a small drink of alcohol)
'for child' is the second definition.
(term for a young child)
(Other definitions for tot that I've seen before include "A wee dram" , "finger, possibly" , "Get the sum for the child" , "quick drink" , "slug?" .)
