From birth, children will begin to explore their own bodies. For example, they will feel their body, know themselves and know their relationship with others and the environment by eating, playing with their hands and feet. This is the beginning of the germination of self-awareness and an important process of children's psychological development. With the growth of children's age, by the age of 3, children begin to have gender awareness, and children will begin to find gender differences and become curious about gender, thus asking some related questions to adults. This is a natural process for children. Children asking these questions just shows that their psychological development process is normal. From this time, parents can guide their children to correctly understand their body and gender and conduct early sex education. Gender education is the first and important step of sex education. At different ages, the theme of sex education is different. It is very important to start sex education consciously after the child is born, which can better promote the child's gender identity and avoid problems in gender development. Some families will raise girls as boys or boys as girls for various reasons after their children are born. The consequences of this may lead to confusion of children's gender consciousness, rejection or ridicule by peers, and difficulty in gender identity when they grow up, which will have a lot of negative effects on children's study, work, life and interpersonal relationships. In the process of raising their children, many parents usually worry about whether some words and deeds of their children are abnormal or whether they will have homosexuality and gender identity problems in the future because their children ask some gender-related questions, or during their normal gender exploration. What is the development process of children's gender consciousness? What can parents do to promote children's gender identity in the process of forming children's gender concept? An important process in the development of gender consciousness is the formation of gender constancy, which is a sign that children acquire the real concept of gender. After the age of 5, it is difficult for women who have no father to understand the characteristics and life of men and the differences between men and women. They are often accompanied by anxiety, shyness and timidity in the process of communicating with the opposite sex during adolescence. Fathers set up the basic image of men for their children. Boys' gender role behaviors and qualities are accomplished by imitating their fathers, while girls understand their gender roles by comparing their parents' behaviors.
