Incidents of sexual abuse of children have occurred from time to time. Tell children which parts of the body are private parts and how to protect their private parts. This is something parents should pay attention to and do well. I have accumulated some experience in the research of children's sexual health education, which parents and kindergarten teachers can refer to: draw boys and girls on a piece of paper, let the children draw by themselves if possible, and let parents draw if the children are young. After painting, let the children mark the private parts of boys and girls with a red pen. Don't say "private parts" directly when using language, because the children don't understand, they should say it. In my experience, some children can correctly mark the private parts of boys and girls, but there are still many children who are not clear about these parts. Their private parts are eyes, hands and feet. These children have no sense of privacy, so they have no sense of self-protection. In the process of making children mark, they are actually helping children to establish the concept of protecting their privacy. After the child marks, if it is not correct, parents should help the child understand it correctly and tell the child that you can't just look at and touch the private parts of others' bodies. A kindergarten teacher told me such a thing: when a girl's mother bathed her child, she found that her child's genitals were a little bruised and asked her child. She also said that sleeping with a boy next to us made us really dizzy. Fortunately, there was nothing serious about the girl's examination later. We apologized again and again, and the boy's parents beat the boy, and the girl's parents stopped. In kindergarten, such things happen from time to time, so for children over 3 years old, such education can be carried out. In addition, in this incident, we can see that both the parents of boys and girls have failed to do their duty to help their children. Boys are beaten and girls may be scolded. They still don't know how to protect their privacy. Beating and scolding children is the performance of parents' incompetence, and it is also the simplest and rudest way of education! After this incident, kindergartens should educate children in this area. Parents should also tell their children that if someone touches their private parts, they should tell their parents immediately. Many children don't know how to do this, so criminals have sexually harmed their children many times. Now there are more and more sexual assaults on boys, so it is also important to educate boys to protect their privacy. I have talked about satisfying children's desire to understand the adult body before. Now I say to teach children to protect their privacy and not to expose their private parts casually. This seems contradictory, but it is not. In the education of children, I think we can satisfy children's curiosity first, and then educate children to protect their privacy, so there will be no conflict.
