At what age is it normal for a little girl to develop breasts?

With the continuous development of society, people's living standards are getting higher and higher. Especially now in the process of raising children, in order for children to grow up healthier, many parents may blindly give their children food supplements. At this time, it may cause children to have precocious puberty, which is not good for the health of the baby. So when do girls' secondary sexual characteristics begin to grow and develop? Mothers with daughters at home should be clear!

1. Breast Growth and Development

For girls, secondary sexual characteristics generally develop earlier than boys, and they will enter the development process around the age of 10. The growth and development of girls' breasts is mainly affected by the estrogen and insulin secreted by the ovaries of the body. Before the age of 10, there is no difference between girls' breasts and boys' breasts. After the age of 10, girls' breasts will gradually grow and develop. When they are about 20 years old, their breast development is close to that of adults.

If a girl's breasts have grown prominently before the age of 10, this may be a typical case of precocious puberty, which may be related to the child's diet, work and rest schedule, and other aspects. If parents are worried, they can take their child to see a doctor for examination.

2. The appearance of hair

Secondary sexual characteristics mainly include the appearance of pubic hair, which will probably appear after the age of 10. Of course, some female friends may not have pubic hair, which is also a normal physiological phenomenon and will not affect female fertility and health. Compared with male pubic hair, armpit hair may grow later, and may not appear until the age of 11-12.

When a girl develops secondary sexual characteristics, she gradually grows into a girl.
