If they want to take care of their brothers and sisters, as the boss, they should have a psychological role, that is, they are already elders. Parents should instill this idea in them and tell them that they are older than their brothers and sisters. They should have that mature heart. At home, maybe their parents are not so careful about their brothers and sisters. At home, maybe their parents don't spend as long as their brothers and sisters, so they should give full play to some of their advantages.
At the same time, we should educate our eldest brother to live in harmony with his younger brothers and sisters, and also give him some rights appropriately. Because he left his younger brothers and sisters idle yesterday and became a talent, we must have a strict personality, because strict sisters can help them establish good study habits and good living habits. At this time, they should be responsible as parents to teach them.
