What do you think, Rahula: What is a mirror for?"
  
  "For reflection, sir."
  
  "In the same way, Rahula, bodily actions, verbal actions, &amp; mental
  actions are to be done with repeated reflection.
  
  "Whenever you want to do a bodily action, you should reflect on it:
  'This bodily action I want to do — would it lead to self-affliction,
  to the affliction of others, or to both? Would it be an unskillful
  bodily action, with painful consequences, painful results?' If, on
  reflection, you know that it would lead to self-affliction, to the
  affliction of others, or to both; it would be an unskillful bodily
  action with painful consequences, painful results, then any bodily
  action of that sort is absolutely unfit for you to do. But if on
  reflection you know that it would not cause affliction... it would be
  a skillful bodily action with pleasant consequences, pleasant results,
  then any bodily action of that sort is fit for you to do.
  
  "While you are doing a bodily action, you should reflect on it: 'This
  bodily action I am doing — is it leading to self-affliction, to the
  affliction of others, or to both? Is it an unskillful bodily action,
  with painful consequences, painful results?' If, on reflection, you
  know that it is leading to self-affliction, to the affliction of
  others, or to both... you should give it up. But if on reflection you
  know that it is not... you may continue with it.
  
  "Having done a bodily action, you should reflect on it: 'This bodily
  action I have done — did it lead to self-affliction, to the affliction
  of others, or to both? Was it an unskillful bodily action, with
  painful consequences, painful results?' If, on reflection, you know
  that it led to self-affliction, to the affliction of others, or to
  both; it was an unskillful bodily action with painful consequences,
  painful results, then you should confess it, reveal it, lay it open to
  the Teacher or to a knowledgeable companion in the holy life. Having
  confessed it... you should exercise restraint in the future. But if on
  reflection you know that it did not lead to affliction... it was a
  skillful bodily action with pleasant consequences, pleasant results,
  then you should stay mentally refreshed &amp; joyful, training day &amp; night
  in skillful mental qualities.


Majjhima  Nikaya 61

Concentrate on whether your behaviour is beneficial to you and them, and if not, adjust it accordingly. 

This is by Kahlil Gibran, not a Buddhist, but the jist of his thought is not un-Buddhist!


  And a woman who held a babe against her bosom said, Speak to us of
  Children.
       And he said: Your children are not your children. They are the sons and daughters of Life’s longing for itself. They come through you
  but not from you, And though they are with you yet they belong not to
  you. You may give them your love but not your thoughts, For they have
  their own thoughts. You may house their bodies but not their souls,
  For their souls dwell in the house of tomorrow, which you cannot
  visit, not even in your dreams. You may strive to be like them, but
  seek not to make them like you. For life goes not backward nor tarries
  with yesterday. You are the bows from which your children as living
  arrows are sent forth. The archer sees the mark upon the path of the
  infinite, and He bends you with His might that His arrows may go swift
  and far. Let your bending in the archer’s hand be for gladness; For
  even as He loves the arrow that flies, so He loves also the bow that
  is stable.


My child is very stubborn, he is 5, and mostly learns through his own errors, not my translation of my errors to him - in my hope he avoids them for himself a-priori. People learn from their own errors for the most part, we can only guide them if they accept guidance. If they don't, guidance will only push them away or to rebellion, better accept if they demand distance, and wait until they see their errors, and return.
