Nursery (6)
I believe the answer is:
creche
'nursery' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for creche that I've seen before include "Place to leave babies" , "A day nursery for children of working parents" , "Day nursery for infants" , "Place where infants are cared for" , "Representation of the nativity scene" .)
