There are three children at home, the eldest 10 years old, the second 9 years old and the third 5 years old. I just can't control it. How can I keep my brother and sister safe?

This child of a few years old, he is confirming his sense of sovereignty, so they should have their own things that others can't want, not just a few children, but special things belong to their parents. So when you buy something, you must make sure who this thing is for. If other children want to play, they must get the consent of the little owner of this thing. Parents should also give different periods of time to take care of a child, so that every child can be taken care of. They will not deliberately attract your attention for the sake of competition, and do many destructive things to make you pay attention to your children. To cultivate the ability of the boss to help, you can ask the boss to come and help when taking care of the youngest child. The boss helped, and then we should praise him and let other diaosi learn from him. Other children can follow this example, ask them to help each other under the care of their parents, and encourage and praise them. In this way, they feel useful, less noisy and willing to help their parents solve other children's problems. . . I hope this works.
