Family is the best classroom.
Sex education at home is the most appropriate. Both adults and children are most relaxed at home, so the pressure to carry out sex education is much less.
Talk about sex naturally
It is very natural to talk about sex and body organs in your own home. When talking about "sex" with children, don't be too mysterious, otherwise adults themselves can't face "sex" calmly, and it is even more difficult to talk about "sex" with babies because of the lack of knowledge and the difficulty in finding effective methods.
Talk about the body with the right name.
When taking a bath, children naturally know the organs of the body and clearly explain the function of each organ, so that for children, saying "penis and vagina" is as natural as saying "nose and mouth" because they are all part of the body.
Answer all questions carefully.
Growing children are always willing to explore and full of questions about things around them, which may make many parents feel headache, especially when asked embarrassing sexual questions. As long as adults answer questions frankly and sincerely, children will naturally accept them innocently.
