When the daughter comes to menstruation for the first time, parents need to communicate with her in an open and inclusive manner, help her understand the process and provide necessary support.

First of all, parents should introduce their daughters to the relevant knowledge of menstruation as detailed as possible, including menstrual cycle, physiological changes, the use of sanitary products and so on. In addition, parents should also explain to their daughters that menstruation is a part of women's physiological cycle and a normal manifestation of women's health.

Secondly, parents need to encourage their daughter to manage herself, teach her to choose sanitary products correctly and tell her how to use them correctly. During the daughter's physiological period, parents should also pay attention to providing necessary support and care, understand her emotional fluctuations, and provide her with some rest and nutrition.

Finally, parents need to send positive physiological and psychological information to their daughter to help her establish positive body awareness and self-awareness. Through active communication and correct guidance, parents can help their daughter through this special period and lay a foundation for her physical and mental health in the future.
