Kindergarten children usually don't fully understand the basic concepts such as gender and reproductive organs, and they are not very good at understanding and processing information related to sex and emotion. At this age, premature contact with sexual content may lead to confusion and discomfort, and may have adverse emotional and psychological effects.
In addition, the role of parents and educators is very important. They should be the first educators of children, providing them with some basic knowledge of physical health and gender equality education, but at this stage, they should not overemphasize sexual behavior and emotional content.
In a word, it is necessary to educate children about basic knowledge of physical health and gender equality, but it may be too early to start sex education in kindergarten. According to the age and development stage of children, appropriate ways and means should be adopted for sex education.
