At what age does a little girl begin to develop

Nowadays, little girls generally develop earlier. If breast development occurs after the age of 9, that is, small lumps appear in the breasts, it is normal. If it occurs before the age of 8, it is considered precocious puberty, but it can be divided into false and true. Breast development is the criterion for the onset of puberty. If menstruation occurs, it means that the development is relatively mature. Let’s learn in detail at what age does a little girl start to develop formally?

There are standards for developmental ages: normal development begins between 8 and 12 years old.

Experts say that girls' puberty sexual development begins with breast development and ends with the onset of menstruation, marking the maturity of development and the end of puberty. This development period generally lasts two to three years, and the average age of onset of development, that is, the beginning of breast development, is 10-12 years old.

There is a normal range for the onset of puberty for girls. Relevant surveys in China show that most girls in large cities begin to develop at the age of 9 years and two months. Generally speaking, the average onset of development for girls in my country is around 10 years old.

Generally speaking, it is normal for breast development to begin between the ages of 8 and 12. If it occurs earlier than 8 years old, it is medically diagnosed as precocious puberty, and if it occurs later than 13 years old, it is called delayed puberty.

In addition, clinically it has been found that some children who develop after the age of 12 have abnormalities, so it is more appropriate to advance the age of late development to 12 years old.

The general early development is related to the improved living standards, environmental pollution, media influence and overnutrition.

Experts say that in the early years, most Chinese girls started to develop in the first and second year of junior high school. But now, many girls start to develop in the fifth and sixth grade of elementary school, or at the age of eleven or twelve. The development age has generally been advanced.

There are many reasons, including improved living standards, better health, better nutrient absorption, environmental factors such as hormone residues in food, soil, and water, heavy metal pollution, and plastic products such as beverage bottles, which also have similar hormone effects and can promote early development. In this information-rich age, television and online media also have a great influence on children. Long-term exposure to a large number of sex-related images can stimulate hormone secretion and advance development. There are also many parents who give their children supplements, such as black chicken soup, ginseng, etc., and children use adult cosmetics, shampoos, etc., which also contain added estrogen ingredients and may become promoters of premature development.

The above is the standard age at which little girls begin to develop. When a child develops too early or too late, as parents, we should carefully observe the changes in our children. Development too early or too late are both abnormal conditions and may cause harm to the child. If necessary, take the child to the hospital for medical treatment.
