Puberty usually begins when girls are 10.5 years old. The first signs are noticed at this stage with the development of breasts. The breasts appear as small lumps under the baby's nipples on either side or one side. During this period, children begin to grow rapidly.

2. The process of growing armpit and pubic hair

At what age do children grow pubic hair? This stage represents the beginning of adrenal hyperactivity. Adrenal hyperplasia is usually normal in girls 8 years of age and older and boys 9 years of age and older. Even if pubic and underarm hair is present in children younger than this age, it's usually nothing to worry about, but it's important to see your pediatrician for a checkup.

3. The process of developing breasts of girls
Most girls start developing breasts around age 11, but about 15% of African American girls and 5% of white girls will start developing breasts before age 8. Girls who start developing breasts before age 8 should be seen by a pediatrician to make sure the signs of development aren't a serious endocrine disorder causing precocious puberty, but most cases are normal. . Girls 14 years of age and underdeveloped breasts should be evaluated for delayed puberty. Breast growth begins with breast buds, hard round areas of tissue under the nipple. The medical term for the onset of breast development: Thelarche. It is normal and common for girls to develop irregular breasts, with one breast growing faster than the other. Some girls will develop the appearance of breast tissue, but without any firm breast buds - lipomastia, and it is really just a collection of fat in the breast area. Lipomastia does not represent puberty.
The most common form of premature breast development actually occurs in toddler girls under 2 years of age. These young girls can develop breast buds that can change size and even disappear altogether. Most of the time, very early breast development in toddler girls is not serious. It's not clear what causes premature breast dryness, but one theory is that ovarian cysts may be releasing hormones that stimulate breast bud growth.
