Many parents can't help yelling at their children when they see them being naughty or doing something they can't stand. In fact, this will not help the child correct his words and deeds, but will make him more curious about this kind of behavior and may continue to do this kind of behavior in the future. This is because for children, he doesn't know why he can't do this. He just lost his temper with their parents and thought it would arouse their anger.
After that, he may continue to do this kind of thing out of challenging his parents' mentality, so when facing young children, he must take a more peaceful way, that is, tell him why he can't do this. For example, in this case, the child messed up his father's paper, which made him very unhappy. Faced with such children, I don't think parents should yell at them, because it won't solve the problem.
Parents can tell their children that it is wrong to do so. In order to impress children, parents can take their children's toys as an analogy, and then throw them away, so that children can feel what it is like to face such a thing. Then through this incident, parents can educate their children and tell them that it is very impolite to tamper with other people's things. In fact, this practice can deepen children's impression of this matter, and it is also more conducive to children to form good habits.
