Puberty for Girls
At puberty, a girl's body goes through many changes, including the newly developed ability to bear children. Some of the physical differences girls notice include:
- The beginning of breast development. The growth of breasts is often the first sign of puberty. As breasts emerge, it's not unusual for one to be larger than the other.
- Hair growth. Expect to notice hair growth in the pubic area and under the arms.
- Change in body shape. A girl's hips tend to get wider and her waist smaller as she goes through puberty. Also, her body will begin to store fat in the stomach, buttocks, and legs.
- The onset of menstruation. Most girls get their periods between 10 and 15 years of age. The first period typically appears between two and three years after breasts start to develop.
