Teach children to think for themselves
Children should learn not only to make their own decisions, but also to have their own opinion. If they argue with you, it means that they have it, and it's fine, even at the exact moment it seems to you quite the opposite. Do not forget that in the long run you should strive for precisely this.
Once I was visiting a friend, and her five-year-old daughter behaved disgustingly, as five-year-olds know how. Mother got angry and told her to leave the room;the girl was upset. But then I was very impressed, because my mother asked my daughter: "Why do you think I was angry with you?" The baby thought for a while, and then muttered: "Because you said to stop, but I did not stop."She herself would not have reflected at that age, why her mother was angry, but she deliberately asked her about it. This is the training of independent thinking.
My girlfriend intuitively caught what technique should be the basis of such training: the questions that you ask the child. It does not matter by and large, what exactly you will ask: what they like more - football or cricket;where, in their opinion, it is better to order a wedding banquet for a hundred people;how to cope with global warming, or what they think about US policy in the Middle East( well, unless the last question should not be asked very small children).You just need to make them think.
At the same time, their ideas need to be tested. Ask: "Why do you think so?" - only not too harshly, so as not to frighten the child. Ask the two-year-old: "Why do you think that dogs should bark?" And a twelve-year-old daughter can ask whether her sneakers are too expensive, in her opinion, from a famous designer.(And if she agrees that the price is really high, ask why she thinks you should spend that much on shoes for her. Maybe it's better to give her a certain amount for clothes, and let her try to figure out what to buy?)
Two-year-old ask: "WHY DO YOU THINK THAT THE DOGS SHOULD LIKE?" AND THE TWELFTH MILITARY DAUGHTER CAN BE INTERESTED, NOT TOO THE ROAD, AT ITS LOOK, KROSOVKA FROM A KNOWN DESIGNER.
Constantly discuss anything with children, ask them any questions.
