When do girls develop puberty?

Everything in today's families revolves around children, especially families with daughters. They not only need to care about their children's food and clothing, but also pay more attention to their children's developmental issues and provide them with timely tutoring in physiological courses. However, because people's living standards have improved a lot now, many mothers have found that their daughters' breasts develop much earlier than when they were young. Is this normal? When do girls usually start to develop?

Developmental period for girls:

Early development type - eight and a half to ten years old

Middle developmental age: 10 to 12 years old

Late-developing type - 12 to 15 years old

As long as it is within this range, whether it develops early or late is normal.

Development of reproductive organs

During puberty, the ovaries of women begin to gradually increase in size. At birth, the ovaries are about 1 cm in diameter and weigh about 1 gram. By the time the ovaries mature during puberty, they can reach 4×3×1 cm and weigh about 5 to 6 grams. Changes in the uterus and fallopian tubes also occur with age. During puberty, the uterus gradually increases in size, and the thickness of the endometrium will also change periodically with the onset of menarche. The fallopian tubes are slender and curved in childhood. After puberty, they become thicker and contain cilia and secretory cells in the lumen, which also changes with the menstrual cycle. During puberty, the vulva becomes plump and raised, and fat accumulates, thus covering the labia minora and vaginal opening, thus protecting the internal genitalia. Due to the influence of estrogen, the vaginal tissue becomes wider and longer, and the vaginal mucosa also becomes thicker.

Posture changes

Generally speaking, female breasts begin to develop around the age of 10. This is the first sign of puberty. The development process is from the nipple bulging before puberty, the formation of the breast nucleus, the bulging of the breast and the areola to the protrusion of the mature breast and nipple. Around the time when breasts begin to develop, armpit hair and pubic hair also begin to develop. This also reflects that the adrenal glands in the body begin to secrete androgens. The pubic and armpit hair of the yellow race is not as developed as that of the white race, and is distributed over a wider area. At the same time, the height of adolescent girls grows rapidly, usually about 10cm. After reaching the peak, the epiphysis heals and the height stops growing. Under the action of estrogen, adolescent women accumulate more fat in their buttocks, breasts, waist, lower abdomen, etc., forming a plump female body shape. By the time they reach maturity, the fat weight of women is twice that of men.

Parents should not only pay attention to the development age of girls, but also help their children through the rebellious period of adolescence. They should pay attention to communicating with their children in a timely manner and be friends with their children instead of ordering them around frequently. This will be of great help to the development of girls and their future mental health. I hope the above can help mothers better understand their daughters.
