Does everyone develop breasts at the same time?
No. It is very normal for some girls to start to develop breasts when they are 7 or 8 years old, while others don't start until they are 12 or 13. Every girl has her own "clock" that her body follows. For example, girls who do gymnastics, dance, track, or some other very active sport may go through puberty at a later age. Even if your development is normal, it is still hard if you seem to be the first one or the last one to develop breasts. Talk to a parent or an adult that you trust and tell him/her how you are feeling. If you develop early, remember that other girls will soon catch up. It is a good idea to talk with your health care provider if you have not started any breast development by the time you are 13 years old.
Your breasts start growing when you begin puberty. Puberty is the name for the time when your body goes through changes and you begin to go from being a child to an adult. During puberty the hormone levels in your body change and this causes your breasts to develop and your menstrual periods to start. Heredity (the way certain characteristics are passed down from generation to generation) and nutrition determine when you are going to begin puberty and develop breasts.
Stages of Breast Development!
The preadolescent breast consists of a small, elevated nipple with no significant underlying breast tissue.
Age 8-14 (usually 11-12)
Breast bud stage; elevation of the breast and nipple as a separate small mound; the areola (the area around the nipple) begins to enlarge, and milk ducts inside the breast begin to grow.
Age 9-15 (usually 12-13)
Enlargement and elevation of the breast and areola (less separation), the areola begins to darken in color, and the milk glands begin to grow.
Age 10-16 (usually13-14)
Projection of the areola and nipple to form a secondary mound.
Age 12-19 (usually 15)
Mature adult breast, projection of the nipple.
Things to Expect:
Your breasts may feel tender, sore, or uncomfortable during puberty.
Your breasts may give out a little bit of milk as they're growing.
One breast might develop faster than the other.
These differences will eventually fad out, and your breasts won't feel as tender.
Because your breasts are new, and not everyone will get them at the same time, they may get a lot of attention. Keep in mind that everyone's breasts are different, no matter their shape or size, your breast are a unique part of you.
Breast shape is determined by the amount of Fatty Tissue it contains. Breasts are made up of Fatty Tissue, Milk Glands, and Milk Ducts (carries the milk from the gland to the Nipple).
Nipples come in all shapes, sizes, and colors. Some girl's nipples get hard and stick out when they're cold, or when they're aroused. Some girls have inverted nipples; inverted nipples stick inward instead of outward.
