From the point of view of some experts, kindergarten children's understanding of gender and gender roles is vague, and they may not have fully formed gender awareness. In this case, instilling the concept and content of sex education into them too early may lead to arousing their interest and curiosity about sex too early and have a negative impact on their physical and mental development.
On the other hand, some experts believe that kindergarten children have acquired certain gender cognition and expression ability. At this stage, through enlightenment and guidance, they can be helped to establish correct gender awareness and values, prevent sexual assault, and thus protect their health and safety.
Therefore, whether to start sex education from kindergarten needs to consider the children's development stage, social and cultural background and other factors, and also needs to pay attention to the scientific, appropriate and effective educational methods and contents.
