First of all, from the perspective of physical development, children's sexual development is in the early stage, and their understanding of sexual knowledge is very limited, and they do not have enough cognitive ability to understand this knowledge. From this point of view, it is really premature to start sex education in kindergartens.
Secondly, from the perspective of psychological development, children's psychological development is not mature enough, their way of thinking is not abstract and logical enough, and they don't have enough thinking ability to understand the content of sex education. If sex education starts in kindergarten, it may bring too much information and pressure to children, which is not conducive to their mental health development.
In addition, from the perspective of parents and society, if sex education is started in kindergarten, it may lead to some unnecessary disputes and negative reactions. Some parents may think that this kind of education is immature, too sensitive and even has some moral problems. The society may also be cautious about this practice, and there may even be some voices of opposition.
To sum up, it may be too early to start sex education in kindergarten. Children are in the early stage of sexual development, and their cognitive and psychological development is not mature enough. From this perspective, premature sex education may have a negative impact on their development. At the same time, parents and society may be cautious about this practice. Therefore, when conducting sex education, we should choose appropriate educational content and methods according to children's age, cognitive and psychological development level to ensure the effectiveness and rationality of sex education.
