The key to establishing a good parent-child relationship lies in "positioning" 1, instead of being a "judge", learn to be a "lawyer". Some parents can't wait to be "judges" when they see that their children have problems, which is very dangerous. Children's inner world is rich and colorful, and parents should actively influence and educate their children. Children can't be educated without knowing their inner world. The first key to understanding children is to care about their self-esteem, safeguard their rights and become their trusted and respected friends. That is, parents should treat their children like "lawyers", understand their inner needs, and always take safeguarding their legitimate rights and interests as their sole purpose. Positioning 2, improper "referee", learn to be a cheerleading team in the arena of life, children can only rely on their own efforts. Parents can neither replace their children, nor should they be "referees" themselves. Instead, they should give their children a strength to maintain a good competitive state, which is the strength of cheerleading. This can help children build self-confidence, which is the core task of family education. Leading right-brain parents to be "cheerleaders" for their children should not only be good at discovering and praising children, but also guide them to face failure correctly and be their comrades-in-arms in the face of setbacks. Positioning 3, improper "animal trainer", learn to be a "mirror" Children can only overcome themselves if they know themselves, but usually they can only know themselves according to other people's feedback. At this time, the "feedback" role of parents, that is, the role of mirrors, is very important.
