Just be patient. If you are currently going through puberty, there are several clues to help you predict whether your breasts will grow naturally. br Look at your mother and grandmothers’ breast sizes. If most women in your family have larger breasts, they are likely to get bigger as you go through puberty.[19] br Examine at your breasts in the mirror. Notice whether the areolas, the area around the nipples, "stick out" a little, meaning they look like little mounds on top of your breasts. If they do, then your breasts are still in their growth phase.[20] br Keep in mind that you may not reach your full breast size until you are in your late teens or even in your early 20s.
