If it's the fault of young children, tell them not to hit their younger brothers or sisters. Hitting people is not what good children should do. If the younger one fights back because the older one bullies the younger one, then both children should be educated. Tell older children to behave like older children, which is an example for younger brothers and sisters. Tell children not to hit people. If you have any opinions, you can speak out. It's wrong to hit people.
Education is especially important for families with two children. No matter how old or young children are, they should be treated equally. We shouldn't indulge and spoil them just because they are young. After a long time, older children will be unbalanced in their hearts, and younger children will be arrogant and unruly. Education should begin at an early age, and children should be taught to be tolerant and treat others, whether relatives or strangers, with the minimum respect and courtesy.
In the TV series "Everything is Fine", it is because of the unfair treatment of mothers that the gap between children is deep, even to the point of hatred. This TV series only teaches parents how to deal with the problems of getting along with their children. They should treat their children impartially and fairly. This is the correct way of education. In addition, mutual understanding between children is also very important. Respect the differences between children and don't compare them, otherwise it will be counterproductive.
