At what age do girls' breasts start to develop?

When girls grow up, they will ask a question. They find it difficult to talk about this question, and even pretend to be disgusted! What is this question? Xiao Ming answered, "Age!" I'll slap you to death! It's the breasts!!! They will ask at what age do girls' breasts begin to develop? A more scientific view is that girls will begin to develop breasts between the ages of 8 and 12. At this time, girls must not be careless in their diet! Let's continue below!

Developmental process:

The first stage (1 to 9 years old): before puberty, breasts have not yet developed.

The second stage (10-11 years old): In the early stage of breast development, the breast bud under the nipple begins to grow and appears as a distinct dome-shaped bulge.

Stage 3 (12-13 years old): The breasts become rounder and shaped like adults, but are still smaller.

Stage 4 (14-15 years old): The breasts enlarge rapidly, and the nipples and areola protrude forward, shaped like small balls. If you are still the same as when you were 13, you need to find out the reason.

The fifth stage (16-18 years old): Normal adult breasts are formed, and the small balls of the nipple and areola merge into the round shape of the breast. Breast development is affected by factors such as region and race, and the time when women's breasts begin to develop varies. For most women, breast development begins between the ages of 8 and 13, and fully matures between the ages of 14 and 18. Breast development usually starts from the left side, and it takes about 3-5 years from the beginning of development to full maturity.

Before puberty, there is no difference in appearance between boys' and girls' breasts. Starting from the age of 7-8, girls' body systems gradually develop. About 2 years later, breasts begin to develop under the combined action of ovarian hormones, pituitary hormones and insulin. The age of breast development also varies from person to person, with an average of 10.8-11.4 years old.

If breasts have not developed after the age of 16, you should be alert to whether it is delayed sexual development or ovarian hypoplasia.

There is great individual variation in breast development in girls. Some girls begin to develop breasts when they are only 8 or 9 years old, while some girls do not begin to develop breasts until they are 16 years old or older. Most girls begin to develop breasts before their first menstrual period, around 9 to 14 years old.

There will be some deviations in the developmental period of every baby. Eight years old is still within the normal range, so mothers don’t need to worry. It's normal.

When a girl's breasts begin to develop at a certain age, she must not be careless in her diet, and girls should not be ashamed and feel embarrassed about breast development. This is your breast development, and you will never regret it in the future! Breasts have always been the second face of a girl, and they are very important. A good cup size can greatly enhance your charm, there is no doubt about it!
