Drink for a child? (3)
I believe the answer is:
tot
'for a child' is the definition.
(term for a young child)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tot that I've seen before include "quick drink" , "Rum measure" , "Child's" , "Youngster; short drink" , "Add; small child" .)
