However majority of parents believe that if you accept your child they will just stay the same. Therefore use 'correcting messages' such as judging, criticizing, preaching, ordering, name-calling, etc.
It was such a humbling experience when I realised that I was doing myself and my children no favours by advising, reassuring, and giving facts.
What's most important is to convey your acceptance through listening and nonintervention. I believe you will be pleasantly suprised at just how many problems children can solve on their own.
