According to what you said, I suggest 1, be patient. He always cries for a reason, no matter what the reason is, but there is always a reason. Cold or hot pain or he is not satisfied in any way may make him cry, so you should be patient and find out the reason and prescribe the right medicine. No matter how young he is, you should treat him as a friend first, and you can't communicate with him in imperative language. 3. Because he is young, I expect you and your family to pay more attention, and you can't beat and scold. 4, you spend more time with him, get along with him more, don't just care about your own business, just mind what you think. You should also set an example for your brother. Over time, he will learn from you unconsciously. 5, take your time, don't be impatient, you can encourage praise and praise his skin, touch him, slowly change him, and correct his bad habits. Of course, you can't blindly obey and develop his waywardness. In a word, it is important for you and your family to set an example. I don't think your mother never lets you take care of your brother. Maybe there is something wrong with your method. You can review your own problems. 7. Gradually let my brother develop a good habit of living, learning and playing, and let him grow up regularly, which becomes a natural habit. This is very important.
