1, tell children how to dress. After children enter adolescence, they need to know very little. As guardians, they should tell their children how to dress, choose clothes that match their age, and choose underwear according to the size of their breasts.

2. Understand the importance of the body. The secondary sexual characteristics of adolescent women are very obvious. Breast bulge, pubic hair growth and menstrual cramps can be very terrible for children. At this time, you must tell your child in advance what to pay attention to during the physiological period and the importance and methods of protecting your body.

3. Teach children to prevent sexual harassment. When children enter adolescence, guardians must tell them how to prevent sexual harassment and never suffer. In addition, it is necessary to tell children that men and women are different, and never go home like when they were children. They can study and eat together, but never live together and keep a safe distance.

4. Let children know physiological knowledge. The body changes gradually in adolescence, and some girls don't know how to deal with it. As guardians, we should guide them correctly, teach them how to do a good job in physical hygiene and explain more physical knowledge.
