Girls usually begin puberty between the ages of 8 and 13 years old. The earliest sign of puberty in most girls is the development of breast "buds," nickel-sized bumps under the nipple. It is not unusual for breast growth to start on one side before the other.
When your daughter starts to go through puberty, her gonads (ovaries) and adrenal glands (glands that sit on top of the kidneys) release hormones. These hormones cause the first signs of puberty, which are breast development, body odor, underarm hair, pubic hair and acne (pimples).
As you go through puberty, you will begin to notice hair growing in new places or thickening in some places. You will grow hair in your armpits, on your legs and in your pubic area near your genitals. This hair will begin thin and straight but will become thicker and sometimes curlier as you get older.
The average age for girls to start puberty is 11, while for boys the average age is 12. But it's perfectly normal for puberty to begin at any point between the ages of 8 and 13 in girls and 9 and 14 in boys.
The most dangerous age is 14. If you know any teenagers this might not come as a surprise, but research has confirmed that risk-taking peaks during this exact moment in mid-adolescence.
As expected, the CDC growth chart shows a plateau in height between 15 and 16 years, reflecting the fact that most girls stop growing around age 15 while others will continue to get taller up to and beyond the age of 16 but not generally past the age of 18.
The signs of puberty include: Growth of pubic and other body hair. Growth spurt. Breast development.
Periods usually begin at around the age of 12. Some girls will start them later, and some earlier – everyone is different. To start with, periods might not happen every month but from the ages of around 16 to 18 most people who menstruate will find their periods are regular.
Increase in Height and Weight
Most girls grow fastest about six months before they start their first period (menarche). You'll probably gain weight in puberty -- most girls do. You may notice more body fat along the upper arms, thighs, and upper back.

Myth: menarche means the end of growth is near
The reality is that the average gain in height after menarche is about 7 cm (3 inches), and it is even greater for girls who menstruate on the early side of normal.
Girls generally begin puberty about two years earlier than boys. Puberty for girls usually starts between the ages of 8 and 13. However, Black and Hispanic girls tend to start puberty earlier than white girls (age 7½ instead of 8).
Most often, it's simply a pattern of growth and development in a family. A guy or girl may find that his or her parent, uncle, aunt, brothers, sisters, or cousins developed later than usual, too. This is called constitutional delay (or being a late bloomer), and it usually doesn't need treatment.
Researchers and physicians hypothesized about possible causes for the increase in early puberty, such as increasing rates of obesity; greater exposure to endocrine-disrupting chemicals found in food, plastics, and personal-care products; and stressful or abusive home environments.
Puberty is usually a question of when, not if. Most cases of delayed puberty are not an actual health problem. Some kids just develop later than others - what we call a “late bloomer.” This has a medical name: “Constitutional Delay of Growth and Puberty.” In many of these cases, late puberty runs in the family.
Your child will experience many changes in their body during this time. For girls, puberty usually occurs between ages 10 to 14, and for boys, between ages 12 to 16.
Puberty is the body's natural process of sexual maturation. Puberty's trigger lies in a small part of the brain called the hypothalamus, a gland that secretes gonadotropin-releasing hormone (GnRH).
According to the U.S. Food and Drug Administration, short stature means an estimated final height below 5 feet 3 inches for boys or 4 feet 11 inches for girls. The average height in the United States is 5 feet 8 inches for men and 5 feet 4 inches for women.
Men are most satisfied when they are 3 inches (8cm) taller than their partners. Another study found that among men, 13.5 percent prefer to date only women shorter than them. But among women, about half (48.9 percent) preferred to date only men taller than them.
What can I do to become taller? Taking good care of yourself — eating well, exercising regularly, and getting plenty of rest — is the best way to stay healthy and help your body reach its natural potential. There's no magic pill for increasing height. In fact, your genes are the major determinant of how tall you'll be.
The onset of adolescence, generally between 12 and 14, is the hardest age for a teenage girl. The hormones of puberty cause her to feel her emotions more intensely but she has not yet developed the reasoning skills to know how to handle them.
"Thirteen-year-olds tend to want to spend more time with their friends than with family members," Dr. Segura says. "They also start to form an identity at this age as they experiment with hobbies, activities, clothes, hairstyles, and music. They try on different identities to see what fits."
