Day nursery (6)
I believe the answer is:
creche
'day nursery' is the definition.
(nursery for children)
This is all the clue.
(Other definitions for creche that I've seen before include "A day nursery for child-minding" , "A day nursery used by working parents" , "Tableau of the Nativity" , "Nursery provided for working parents" , "Child-minding establishment for working parents" .)
