Stages of puberty in girls
1. Pre-puberty (around 8-10 years old): In this stage, girls may begin to develop some breast tissue, but other physical changes are less noticeable. They might also notice body odor and an increase in hair growth on their arms and legs, but not pubic hair.
2. The first signs of puberty (around 10-13 years old): This is when breast development (called "budding") starts, and pubic hair begins to grow. In addition, girls may experience a rapid growth spurt at this stage, increasing in height and weight.
3. Developing further (around 11-15 years old): As puberty progresses, the breasts become fuller and rounder. Pubic hair will become thicker and may start to appear around the inner thighs. Underarm hair starts to grow, and the areola (the circular area around the nipple) may darken.
4. Menstruation begins (usually between ages 12-13): The first period (called menarche) generally occurs within a year or two of breast budding. Periods may be irregular at first, taking several years to become more consistent.
5. Continued development (around 13-17 years old): Girls may continue to grow in height and fill out in size throughout their teen years. Hips may become wider, and body-fat distribution can change, leading to a curvier figure.
6. Completion of puberty (around 14-18 years old): By this stage, most girls have reached their adult height, breast size, and body shape. Pubic hair may extend to the thighs, and periods should become more regular.
It is important to remember that every girl experiences puberty differently, and there is a wide range of normal development. The stages and ages mentioned here are approximate and can vary from one individual to another.
