It’s important that you discuss menstruation with your daughter as early as possible as some girls can get their periods as young as eight or nine. Also, many girls in her class will have the facts, some of which will be wrong. It’s important to set the record straight and offer her some basic advise to set her mind at ease.
Sit her down one day when it is just the two of you and you can be relaxed and tell her about the facts of menstruation. Tell her it’s all very normal and it happens to every girl. It can be a good idea to also give her some reading material that she can look at when she is on her own.
Make sure that she understands that she can come to you at any time with any questions or concerns she may have.
