Don't worry about scale.
Generally speaking, children's mastery of knowledge is cyclical and gradual. Even if parents educate more knowledge, the amount absorbed by children is limited. When encountering some large-scale problems, parents don't have to worry too much, just tell the answers with a normal heart, seize the opportunities in daily life, and let the children understand.
Don't shy away from children's sexual problems
In infancy, especially after puberty, children are full of curiosity and ignorance about "sex". At this time, don't refuse to answer when the child has relevant questions, otherwise the child's questioning will not only dispel the child's doubts, but will increase the child's curiosity. We should face them correctly and tell them the relevant answers.
Talk like friends.
For older children, we should give full consideration to their psychology when conducting sex education. After all, such children don't agree with the didactic education. They can communicate with their children in the dialogue with friends, which makes them feel more equal and easier to be accepted by children.
Query information together
When children ask questions, if parents can't give accurate answers, they can search for information together, search for answers together, and discuss together, so as to prevent children from blindly searching and entering some websites by mistake because they can't get accurate answers.
