Children naturally recognize three major areas from an early age: first, the relationship between themselves and themselves; One is the relationship between oneself and matter; One is their relationship with them.

Therefore, children can be allowed to be with other children over 1 year old. Children aged 2-3 are not only exploring their relationship with material things, but also exploring their relationship with others, especially the matter of establishing friendship.

Pay attention to a person's good relationship with himself. Pay attention to the connection between people. This feeling fascinates children, so children in this period are very concerned about who plays with themselves and who doesn't. Who is your friend and who is not your friend, which has caused a lot of happiness and trouble.

In any case, happiness and troubles will bring children's love and pursuit of friendship and lay a good psychological foundation for practicing joining the league in the future.

The pursuit of friendship makes them begin to practice friendship, which is a vital development content for human beings, which can only get survival opportunities by providing services to others.

If a child does not join the group in the group, but he has a friend, he will also develop social skills.

If the child doesn't have any friends outside the group and becomes a person ignored by the group, then he will definitely have problems in interpersonal relations and social skills in the future, which will lead to difficulties in survival. At this time, adults need to find ways to help children.
