Photos of the development process of first grade girls

Today's girls are full of curiosity about their own body growth and development, so some middle school girls want to know how girls' breasts develop. I believe everyone will know after reading the following description.

1. First, middle school girls generally enter puberty. When girls enter puberty, the first part of their body to grow and develop is their breasts. After puberty, under the influence of estrogen, girls' breasts begin to grow and develop. At this time, in addition to the continuous growth of many long and thin mammary ducts in the breasts, a lot of fat is accumulated. Because the mammary gland tissue is hard and the fat tissue is soft, the breasts become more protruding and elastic, which becomes a sign of female maturity.

2. Second, there are great individual differences in breast development among girls. Some girls start growing and developing at the age of 8 or 9, while others don't start growing and developing until they are 16 or older. Most girls begin to grow and develop before their menarche, around 9-14 years old.

3. Third, when a girl's breasts begin to grow, the mammary glands that make up the breasts and the surrounding fat tissue form a button-like bulge on the nipple and the surrounding nipple, making the nipple and nipple protrude, and the nipple begins to enlarge. Then the nipple protrusion becomes more obvious and gradually becomes fuller, eventually growing into the shape of an adult breast.

Common breast development issues

The breasts of adolescent girls will gradually grow. Due to the influence of estrogen, the mammary glands will begin to grow and develop. In addition, there is a lot of fat in the breasts. The mammary gland tissue will be harder, but the fat tissue will be much softer. The breasts of first-year girls have already begun to bulge and have a certain degree of elasticity. Some girls may feel bad about this kind of change, but in fact you need to recognize this kind of change and don't care about other people's opinions.

Girls in the first grade of junior high school must not feel guilty when their breasts are developing. They should often lower their heads and hunch their chests when walking. This will always affect their growth and development, and hunching the chest too much will lead to hunchback. There are differences in the timing of breast development among first-year junior high school girls, and diet and genetic inheritance are related to this. Some girls may have breast development at the age of eight or nine, while others may not begin to develop until the age of 12. Also, the growth rate is different, some people grow faster; some may grow slower.

The first stage of breast development for first-year junior high school girls is mainly characterized by nipple protrusion and nipple enlargement. When the nipples first emerge, they are very tender and sensitive, and the nipples are prone to inflammation. Therefore, you must wear a pure cotton camisole to protect your nipples. In the second stage, a nucleus appears in your breast and it is painful to touch. At this time, the breasts need more care. By the age of 12, many girls have already started their periods, but their breasts are still in the process of puberty.

During the puberty of breast development, girls in the first grade of junior high school may often experience breast pain, nipple itching, etc. before and after their menstrual period due to endocrine influences. When encountering this situation, do not squeeze or pick your nipples to avoid infection. Clean nipples, teats and breasts frequently. The glandular ducts in the nipple are rich and colorful, and they secrete oil to protect the skin, but they also cause stains, so you must pay attention to maintaining breast hygiene.
