Children like to imitate and are influenced by age and psychological characteristics. They not only learn knowledge and life experience from adults, but also learn the way they love others. Therefore, as parents, it is an obligation to create a warm and harmonious environment for children, so that children can feel affection, care and love, thus forming a healthy and stable mood. Children live in family, kindergarten and social environment. The warmth in the family, the relaxation and equality of peers, and the mutual help and love in the society can all make children feel cared for and cared for, thus gaining a better sense of security and developing their social skills better. Based on this, the author believes that in a two-child family, parents especially need to create a warm and harmonious emotional environment for their children, so that the two children can care about each other, infect them with their own actions, let them learn how to love a person, and let the two children care about each other in the process of imitating their parents' words and deeds, especially the first-born child will love the two children very much and warm up their feelings. At the same time, the warm and harmonious emotional environment created by parents for their children can also effectively alleviate the psychological emotions of the first-born children and reduce the impact of the birth of two children on their life, emotions and mental health. Therefore, in the family education of two children, parents should create a warm and harmonious emotional environment for their children.

(2) Help children accurately locate their roles.

Everyone plays different roles in social life, and understanding the true meaning of each role is an important beginning to assume role responsibility. However, children don't know enough about the meaning of different roles and haven't mastered the ability of different roles, so they can't change roles smoothly. They need the guidance of adults more. For the first-born child in a two-child family, parents should inform their brothers and sisters in advance that they will come to this family and become brothers and sisters. At this time, parents can help their first-born children understand the roles of brothers and sisters through games, so that they can adapt to their new identities in advance. For example, parents and their first-born children play a doll's house game together, so that they can play the role of brothers and sisters in the game, leaving them more time to experience, understand and adapt to the change of identity. At the same time, we should also give the two children independent space, give them the opportunity to realize their own value, reduce their dependence, and let them grow up confidently and happily. Although there are some problems in the education of two-child families, with the joint efforts of parents and kindergarten teachers, I believe they can all grow up healthily and happily.

Communicate effectively with the first-born children.

In a two-child family, because of the arrival of two children, the elders in the family are busy taking care of the lives of the two children, sometimes ignoring the communication and education with the first-born child, which leads to the imbalance of the first-born child and even dissatisfaction with the arrival of his younger brother and sister. At this time, parents need to pay attention to the psychological changes of their first-born children and educate them. Take a child I came into contact with as an example. In order to reduce the psychological burden of the eldest son and enable him to accept his new identity-brother, his mother not only worked emotionally, materially and ideologically, but also bought a picture book "I want to be a brother" for parent-child reading, telling interesting stories about his mother's childhood with his uncle, and his father and aunt played games together when they were young, which gradually made him realize that he would have a younger brother or sister around. However, even under such circumstances, after my sister was born, my brother was still unhappy and thought that my mother's care and love had been taken away by my sister. So this mother often talks to him, communicates with him, tells interesting stories about his childhood, and tells how his mother took care of him when he was a child. In this way, my brother loves his sister more and more, and he can take the initiative to take care of his sister even if the adults are busy. From this case, we can see that in the family education of two children, communication with the first-born child is of great significance to the healthy growth of children's body and mind.
