Piece of good advice from father (3)

I believe the answer is:

dad

'father' is the definition.
(informal term for father)

'piece of good advice from' is the wordplay.
'piece of' indicates the answer is hidden within the clue.
'DAD' is hidden within 'good advice from'.

(Other definitions for dad that I've seen before include "Popular and informal father" , "Old man" , "Papa" , "Pop, pater" , "Mum's mate" .)

I've seen this clue in the Evening Standard.
