Good parent-child interaction is conducive to the physical and mental health of young children. Children are young, mentally vulnerable and sensitive, and feel fear and anxiety about the unknown environment. In many cases, they need the comfort and company of parents. For young children, the parents are the closest people to the children and the people they trust the most. No one can replace the parent's company. With the company of parents, children will feel safe enough to devote themselves to games and learning. However, many parents hand over their children to kindergartens, allowing them to face unfamiliar environments on their own. Without the company of parents, young children will feel lonely and helpless, unable to fully engage in learning and entertainment. Not only is it difficult to improve learning efficiency and quality, but also affects physical and mental health. Parent-child companionship activities in kindergartens can reduce children's anxiety, relieve their unhealthy emotions, and enhance their sense of security. The effective development of various parent-child activities can enhance the parent-child relationship, allow children to learn more at ease, develop good habits, form good moral qualities, and promote children's all-round development.
