Daughter stopping one bad habit gets counselling (6)
I believe the answer is:
advice
'counselling' is the definition.
(I've seen this before)
'daughter stopping one bad habit' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'stopping' indicates putting letters inside (stopping can mean blocking a gap).
'one' becomes 'a' (a thing is one thing).
'bad habit' becomes 'vice' (a sin or weakness).
'a'+'vice'='avice'
'd' put inside 'avice' is 'ADVICE'.
'gets' acts as a link.
(Other definitions for advice that I've seen before include "Counsel given" , "'Counsel, guidance (6)'" , "Guidance; delivery note" , "Opinion given about what to do" , "Supposed words of wisdom" .)
