First of all, starting sex education in kindergarten may cause children panic and confusion. Children in early childhood do not have enough cognitive and understanding abilities, and their understanding of sexual knowledge is very limited. If sexual knowledge is taught at this stage, it may bring too much information and cognitive pressure to children. They may feel confused, shy or uneasy, and their understanding of sexual knowledge may be biased.
Secondly, starting sex education in kindergarten may cause resentment among parents. Many parents believe that sex education should be carried out by families, not schools. If sex education is carried out in kindergartens, it is likely to cause parents' dissatisfaction and opposition, which will lead to the intensification of the contradiction between home and school.
Finally, starting sex education in kindergartens may cause some safety problems. The educational level and professional ability of kindergarten teachers may not meet enough standards. They may make some inappropriate remarks or behaviors in sex education, and may even cause some sexual assault.
To sum up, it is not appropriate to start sex education in kindergarten. Professionals should conduct sex education after children enter adolescence to ensure the effectiveness and safety of sex education.
