Some volunteer babysitters (5)

I believe the answer is:

aunts

(Other definitions for aunts that I've seen before include "Elderly female relations" , "Relatives get bad US tan" , "relatively speaking" , "Relatives get an odd US tan" , "Parents' sisters" .)

I've seen this clue in The New York Times.
