Let the subject come up naturally, while watching TV or riding in the car. You'll find that it's easier for your child to absorb information a little at a time. You'll observe external changes, such as breast development and a growth spurt, while internally, the reproductive organs are also maturing. This leads up to the main event-menstruation. Let your daughter know that menstruating, or getting her period, is a natural, positive step toward becoming a woman.
Many girls start with pads to become familiar with their menstrual flow.
By then, her body is mature enough to use a tampon. Inserting the tampon is not a problem, because the vaginal opening is flexible, and is only partially covered by the hymen. The opening that allows menstrual fluid out, also allows a tampon to be inserted. Please note that tampons do not affect virginity. A virgin is someone who has not had sexual intercourse.
