More and more parents are busy with their work and the elderly take care of their children. Parents spend less time with their children, which seriously affects the development of parent-child relationship. Lack of parental care is not conducive to the healthy growth of children. Li Shenglan pointed out in research on Cooperative parenting between kindergarten and family community that parent-child activity is an important part of communication between kindergarten and family. "Parents come to kindergarten to participate in parent-child activities" accounted for 84% of kindergarten education. Parents participate in parent-child activities in kindergarten. In the process of activities, they interact with children, observe children's behavior, feel children's changes, so as to understand the kindergarten intuitively and evaluate children's development correctly. Parent-child activities help to strengthen the emotional communication between parents and children, establish a good parent-child relationship, and create a good family atmosphere. Through the normal communication between teachers and parents, it can be found that some parents have misunderstandings in the way of educating their children and do not understand the psychological characteristics of their children at all stages. With the help of teachers, parents can strengthen and update the concepts and methods of early childhood education through parent-child activities in kindergarten to understand the growth characteristics of children. Parent child activities provide parents with opportunities to learn and communicate with teachers and other parents, which is of great significance to parents.
