Children’s home parents are not expected to visit? (9)
I believe the answer is:
orphanage
'children's home' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
(Other definitions for orphanage that I've seen before include "with deprived children" , "special home" , "Children's home" , "home for little Annie" , "Parentless children's institution" .)
