Parents need to tell their younger brother clearly that their elder sister is his elder and they need to listen to her like their parents. Secondly, my sister used some means to make my brother willingly obey. For example, if your brother is disobedient, you should gain his trust first, and then help him do what he likes, so that he can feel that you are his most reliable, so that he can listen to what you say slowly. At this time, you should play some games with your brother that he likes to play. During the game, you can praise your brother, saying that he is too smart and plays better than his sister. At this time, you can ask your brother. After you listen to your sister, she will definitely buy you the best toys. My sister will also teach you to draw. You think this is ok, and my brother listens to you happily.

In educating children, parents need to lead by example.
