Stage 1 is the stage before puberty begins. The breasts have not yet started to develop. The nipples are partley raised. If not, the breasts are flat.
Stage 2: Breasts Buds Develop
Breast Buds start developing. A small, button like breast bud forms under each nipple. The areola gets bigger and wider.
Stage 3: Development continues
The breasts get larger. The areola gets larger. They stand out more from the chest. You also may notice that the nipples are getting larger. In this stage the breasts are adult in shape but smaller than they will be when you are an adult. Stage 3 may take 2 months or even 2 years.
Stage 4: Nipple and areola form mound
The Areola and Nipple continue to enlarge. They form a seperate mound on the breast.
They stick out above the rest of the breast. The breasts are often pointy at this stage. Some girls skip this stage.
Stage 5: Adult
The nipple and areola no longer form a seperate mound on the breast. This is the adult stage. The breasts are fully developed. Some girls breasts have reached thier adult size but they may not be very large.
