Children's chest development standards

We all know that breast development is particularly important for girls. When girls are in their teens, their breasts begin to develop. During the development of girls' breasts, it is important to educate them about the knowledge of development. It is time to dress children in developmental clothes and tell them to be hygienic. However, there is also a development standard for girls' development. The following editor will introduce the standards for children's breast development.

If a girl is over 8 years old and her breasts are just beginning to develop (touch both breasts and feel the coin-sized nuclei), it is normal, because it usually takes 2-3 years for a girl to develop breasts and have her first menstruation. She is now 8 years old, and she should be 11 years old when she has her first menstruation, which is normal.

Suggestions:

When a girl is 9 to 10 years old, her breasts begin to develop, the breast tissue increases, and the breast shape also increases. After 4 to 5 years of development, that is, around the age of 15, the breasts have taken shape, become fuller, and the nipples become larger, thus showing the unique curves of women.

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. Girls will experience breast hyperplasia when they reach the age of 10-11, at which time a breast nucleus will be formed. When you touch it with your hand, you will find a nodule or a small lump, and it will also feel tender.

The third stage (12-13 years old): When girls reach the age of 12-13, the mammary ducts and subcutaneous fat will slowly increase, the breasts will gradually swell and become elastic, the breasts will become round and shaped like adults, but still small.

Stage 4 (14-15 years old): The breasts enlarge rapidly, and the nipples and areola protrude forward, shaped like small balls.

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.

Tips: According to surveys, the average age of breast development for girls is 10.8-11.4 years old. It should be noted that if a girl is over 16 years old and her breasts have not developed, parents must be alert to whether it is due to delayed sexual development or ovarian hypoplasia.
