How large will my daughter’s breasts get?

Once a girl’s breasts begin developing, she understandably will be interested in how big they’ll become. However, there’s no surefire way to predict. What you can explain to your daughter is that breast size is mainly determined by genetics. As a consequence, there is no potion she can drink and no lotion she can apply that will noticeably affect the size of her breasts. (Trust me, if anyone develops such a product, it will be all over the news!)
