I think it may be too early. Children in early childhood often have not formed gender consciousness and sexual concept, so it is difficult to understand and accept the content and significance of sex education. In addition, kindergarten education should focus on mastering basic knowledge and promoting physical and mental development, rather than sex education.

However, in kindergarten, children can be properly taught some knowledge about physical hygiene, such as how to keep their bodies clean and healthy, which does not involve sex, but can lay the foundation for subsequent sex education.

Sex education should be carried out gradually in preschool and primary schools. With the age and physical development of children, more complex and sensitive sex education issues should be discussed gradually. When conducting sex education, we should adopt appropriate educational contents and methods according to children's age and cognitive level, constantly improve children's sexual knowledge and gender awareness, and guide children to form healthy, positive and responsible sexual concepts and values. At the same time, sex education also needs to pay attention to the cooperation between family and school, pay attention to and guide children's sex education together, and effectively protect children's healthy growth.
