Drinks for babies (4)
I believe the answer is:
tots
This clue is a double definition.
'drinks' is the first definition.
(I have seen 'Little drinks' mean 'tots' so perhaps 'drinks' could also mean 'tots')
'babies' is the second definition.
(tot can mean a young child)
'for' acts as a link.
(Other definitions for tots that I've seen before include "Young children - shorts" , "Adds up like small children" , "Party drinks" , "Babies" , "Adds up for the youngsters" .)
