Drinks required for little ones (4)
I believe the answer is:
tots
I believe this is a double definition.
'drinks' is the first definition.
(I have seen 'Little drinks' mean 'tots' so perhaps 'drinks' could also mean 'tots')
'for little ones' is the second definition.
(I've seen this in another clue)
'required' acts as a link.
(Other definitions for tots that I've seen before include "Sailors' drams" , "Adds up for the youngsters" , "Young children - shorts" , "Babies" , "Little children" .)
