There are two children in my family, so I will be a little at a loss when allocating resources, because I am afraid that the other child will feel partial to each other. Therefore, I have taught my children to know how to share since I was a child. At first, my children were not happy. Later, once the child happened to do something wrong, I punished him to think about it. Later, my other child offered snacks to the child I was thinking about. At that moment, the two children seemed to turn swords into enemies. From then on, they shared things together every time they ate. Later, I asked them why they shared things, and they said that they would be happy as long as they were happy with each other, so I think this is also the reason why they understand the importance of sharing.
