Do okay with daughter kept in (8)
I believe the answer is:
confined
'kept in' is the definition.
'do okay with daughter' is the wordplay.
'do' becomes 'con'.
'okay' becomes 'fine' (both are ways of saying 'yes').
'with' says to put letters next to each other.
'daughter' becomes 'd'.
'con'+'fine'+'d'='CONFINED'
(Other definitions for confined that I've seen before include "Imprisoned or limited in space" , "Kept within limits" , "Enclosed, cramped" , "Not free to move about" , "locked up" .)
