Children between the ages of 4 and 5 gradually develop from playing and playing alone to cooperating with other children in interactive, cooperative activities, and in the process, begin to interact with other children. Lack of friendship partners or rejection by peers during childhood can not only cause emotional damage and adverse psychological symptoms such as shyness, fear, and low self-esteem, but also affect the development of other personalities later in life. The child’s self-evaluation during this period is often influenced by the cues of others, is more dependent on the evaluation of adult authority figures, and is unquestioning of adult evaluations. In other words, the relationship and the attitude of the parents or other caregivers with him during this period will directly affect the child’s perception of himself and, indirectly, his confidence in himself. During this period, children who lack contact with their peers do not have sufficient time to practice interaction skills. On the other hand, parents do not communicate enough with their children, so the child will feel neglected, then the child may take the wrong way to attract attention, such as mischief, then if not complemented by the correct guidance, just criticism, scolding, will make him feel the disgust of others, he will show more self-blame “I’m not good”, “I’m not good”. “no one loves me anymore”, thus creating deep guilt. Over time, this is not conducive to children learning how to better handle these things in their lives, making it difficult to maintain an interest in exploring, and instead they may become more withdrawn and closed off. They may even take out the pressure from their parents on other children or adults, or on toys, and engage in more peer-to-peer conflict and toy destruction. As you can see, emotional damage in childhood can have a negative impact on later character if not properly guided.
