I think it's good to meet different types of children. Learning from each other's strengths is conducive to the improvement of children's personality. Friends are actually an ecological environment. For children, having a group of different friends is healthier and more conducive to growth than homogenization and similarity. Don't make a fuss, pay attention to remind children to be civilized and pay attention to the occasion. In addition to absorbing each other's advantages, children will inevitably infect each other with some minor problems. It can improve immunity after recovery.
Being "bad" by friends is actually not that bad. If it is changed, it is also a desensitization process, and children will be more sensible and will not make similar problems again. Although children will get better if they like someone, they will change when they say it. Even for a piece of bubble gum, a toy will become bitter immediately. Boys are often stupid, and when they are in a hurry, they will swing their fists, while girls are more strategic. They can break up several times a day.
