Make a point of disturbing her naps (7)
I believe the answer is:
sharpen
'make a point' is the definition.
(I've seen this in another clue)
'disturbing her naps' is the wordplay.
'disturbing' indicates an anagram (I've seen this in other clues).
'her'+'naps'='hernaps'
'hernaps' with letters rearranged gives 'SHARPEN'.
'of' is the link.
(Other definitions for sharpen that I've seen before include "Raise pitch of" , "Make more acute" , "Restore edge to knife" , "instrument secured by former nurse" , "Get keen" .)
