1. Understanding and respect: Understand and respect your brother's feelings and ideas, and don't force him to accept his brother.
2. Communication: communicate with my brother, understand his thoughts and feelings, and try to understand his position.
3. Establish benign interaction: Encourage the elder brother and younger brother to have benign interaction, such as playing and playing games together, so as to establish more contacts between them.
4. Give attention and love: Try to give your younger brother enough attention and love, so that they can feel valued and cared for.
5. Seek professional help: If the problem is serious, you can consider seeking professional help, such as psychological counseling.
It should be noted that each child is an independent individual, and it takes time for them to get along. Parents need patience and understanding, and don't force or force their children to accept brotherhood.
