What are the characteristics of girls' development?

There is an old Chinese saying that goes, "Girls change a lot when they grow up." In fact, women undergo different changes at each stage of their development. In order to prevent poor development, it is necessary for us to understand the developmental characteristics of girls. We hope that after understanding these characteristics, we can actively prevent the occurrence of other diseases.

For girls, under normal conditions, they will begin to show signs of growth after the age of ten. Between the ages of ten and eleven, their height and weight will grow rapidly. So at this time girls often outnumber boys. By this time, the breasts have already changed. The nipples will be slightly raised. The nipples will change color slightly and pubic hair will begin to grow. Of course it's still very sparse. After the age of eleven or twelve, the breasts will begin to swell. At this time, the pubic hair is already very thick, but not as long as that of adults and is not distributed over a wide area. The external genitalia will also begin to change. Some people think that girls' labia will become exposed when they grow up, but in fact it varies from person to person. When we look at photos online, we find that some people still have retracted labia at the age of eighteen. Some people's hidden lips are exposed at 9 o'clock, but in fact it is just a difference in personal body shape. Whether the labia are exposed or not is not closely related to puberty development. It is even possible that the labia majora develop outside during childhood and then "shrink" back during puberty due to changes in body shape. Generally speaking, a girl's vulva will not have any obvious changes in appearance after entering puberty. Just like a boy's penis and a man's penis, they are just different in size, not much different. Of course, there will be some changes in the color and proportions of the vulva, but this also varies from person to person.

But one thing is true, that is, when a girl is born, her vulva is just a slit. As for why some people's labia become larger and some people's clitoris become larger, these changes are very complicated and do not necessarily start during puberty. Just like our noses and eyes are of different sizes.

From the outside, menstruation occurs only when the breasts and genitals develop to a certain extent. To put it more deeply, a woman's menstruation marks the beginning of the maturation of her internal reproductive organs, such as the ovaries and uterus. This means that she can have children, but of course this will have to wait until her external reproductive organs develop to a certain extent. So menstruation must occur some time after puberty. Generally, girls begin to enter the developmental stage at the age of ten to eleven, and girls at the age of eleven or twelve will show obvious secondary sexual characteristics in appearance. Girls usually start menstruating when they are twelve or thirteen years old. In rural areas, it's usually later, [Note: many ethnic minorities develop earlier] around fourteen or fifteen years old. Unlike boys, girls develop early, but develop slowly and end early, while boys develop late, develop quickly and end late. So boys have much more room for development than girls. It is precisely because of this difference in boys' delayed development that many men who have never seen a girl who has just given birth will have thoughts like "it's not good for a girl to not have pubic hair at the age of sixteen." In fact, most boys have full pubic hair by the age of sixteen.

The above are the characteristics of girls' development. We can clearly see that at different age stages, height, weight, and physiological aspects will undergo different changes. After understanding the above knowledge, we can judge for ourselves whether we are developing normally.
