My teenage daughter has reached the age of puberty. How do I explain her about the menstrual cycles?

be normal about it when you bring up the topic. tell her that there are certain changes that people go through, that is why girls look different from women, and boys look different from men. broach the subject casually, like when you both are sitting relaxed at home. you can prepare a sanitary kit and give her, while talking. keep a few pads, some cotton, a new set of underwears, some body mist and wipes for her. tell her about the changes, but not in too much detail. you can ask her to carry this bag with her at all times, so that she is always ready whenever she starts the period.
