Children in Sweden are obviously different. 15 of the children, 1 1, depicts the reproduction map caused by sexual intercourse; They also know the concepts of contraception, childbirth and origin. In their photos, parents and babies are smiling! Regarding the development of children's sexual psychology, there is a study that can prove it. 1974, Patricia Basalokoqi, a sex education expert, went to Sweden to study the "compulsory" sex education implemented in Swedish schools, trying to find out whether this kind of education for children aged seven or eight can convey sexual knowledge more correctly than the open discussion method in the United States. She first asked a group of American sophomores and a group of Swedish sophomores of the same grade to draw pictures of "Where babies come from" and "How they were born", and then asked them to explain. Most American children talk about God's will, eating certain foods and even dreaming. They didn't talk about any kind of male role except one child who said that "the doctor cut off his mother and her mother was in pain". Children in Sweden are obviously different. 15 of the children, 1 1, depicts the reproduction map caused by sexual intercourse; They also know the concepts of contraception, childbirth and origin. In their photos, parents and babies are smiling! What this survey reveals is that parents should answer their children's reproductive doubts as simply, honestly and clearly as possible. In order to understand the children's understanding ability, Dr. Anne Sibanstein asked them about the concept of the origin of babies. It is found that children can often tell the truth about their birth, which may lead to misunderstanding, confusion and even panic among parents. If you are also worried about children being so precocious, you might as well use the reproduction process of "eggs" or "seeds" to explain production. Eggs are familiar foods, and seeds are known to us-the origin of plants growing in soil. You should be able to speak freely and clearly. Children aged three or four are mostly in the first and second stages of their understanding of sex. Another feature is that you will fall in love with your parents who are different from your own sex, and even be jealous of the same sex. Although they can't have adult thoughts, there is no doubt that they already know "sex", which can show tenderness, love and jealousy-showing that all children's emotions are related to the "sexual desire" of Hua Song people. Most children of this age are active (the "moral" principle of being a man has not yet been developed). When they are in bed, they will try to get close to their parents, hoping to take a bath with them, watching them get dressed, or touching their genitals. If you encounter a similar situation, please don't yell at him or give him a hard stare, because it's just curiosity. As long as you set the rules for him, the child usually knows how to do it. Between the ages of five and seven, children's attitudes towards their parents may change. They gave up the idea of "marrying" their mother or father and decided to be closer to their same-sex parents; At this moment, they also began to identify with their masculinity or femininity, and gradually entered the homosexual feeling of despising the opposite sex. Masturbation is quite common at this age. If children openly touch their genitals, this is the right time to talk about it. Besides, you should also assure him that it is not abnormal and explain that it is something people can do in private.
