Small child's small drink (3)

I believe the answer is:

tot

I believe this clue is a double definition.

'small child's' is the first definition.
(tot can mean a baby or toddler)

'small drink' is the second definition.
(I've seen this in another clue)

(Other definitions for tot that I've seen before include "Child; measure of spirits" , "finger, possibly" , "Add the little child?" , "Drop" , "Youngster; short drink" .)

I've seen this clue in The Times.
