As a parent, how do I modify my child's behaviour without diminishing their character or self -esteem?
The key is to intently listen to them expressing what they have done, thereby inviting them to turn back towards their own wisdom … so that they will realize that they are out of alignment with who they really are. What is helpful is having good listening skills and to demonstrate that you care about them and to bring down your own wall of judgment towards them.
By being non-judgmental towards your child and by putting yourself on their side of the table they will soon become more comfortable and their defensiveness towards the matter will start dissolving. There is only one effective method of communication, and that is the expression of love. All other methods tend to confuse what is really important. It is only when we have a feeling of support and non-judgment that we can fully open ourselves up to the messages that another is sending to us. From that place a strong sense of communication is allowed so that the other may be influenced in a positive manner.
