First, don't get involved.
Conflicts between children and friends, or between adults and friends, are very common. After all, everyone is a unique individual, and it is understandable to have different ideas or deviations about some things. However, most children have simple minds. Even if there are contradictions, what they say most is that they won't play with each other. However, in a couple of days, they will find that their children and friends have made up again. This is because most children don't hold grudges. Therefore, parents should not tell their children about each other's shortcomings and bad places, which will affect their future character formation and development.
Second, help children analyze the reasons.
So parents can help their children analyze the causes of things. For example, they can ask their children what is the reason for the conflict between two people, so as to judge who is the real mistake according to this reason. If your child is wrong, ask your child to apologize to his friend. Only in this way can the feelings between two people be deepened. In addition, it is necessary to properly tell children some truth. Children and adults will have conflicts with their friends. At this time, you must judge whether it is your own fault or someone else's fault. If it's someone else's fault, we should live in peace. If we always say not to play with others, it will hurt others' hearts.
