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. It's also common for breast buds to be somewhat tender or sore.
Many young women experience pain as their breasts grow and this is nothing to worry about. Breasts develop as the hormones estrogen and progesterone are released at puberty. These hormones make the breast tissue grow. As it does, the surrounding skin may stretch, which is one reason breasts can hurt when they grow.
Hormones are making your breasts sore.
Breasts become sore three to five days prior to the beginning of a menstrual period and stop hurting after it starts. This is due to a rise in estrogen and progesterone right before your period. These hormones cause your breasts to swell and can lead to tenderness.
Breast Development
It is not unusual for breast growth to start on one side before the other. It's also common for breast buds to be somewhat tender or sore. Uneven breast growth and soreness are both totally normal and usually improve with time.
Is it true that when you or another person touches your boobs, they will get bigger? No, it's not true. Touching or massaging breasts does not make them grow.
At what age do girls stop growing? Girls tend to have a major growth spurt between the ages of 10 and 14. Most will have reached their adult height by the time they are 14 or 15 years old. This major growth spurt happens during the phase of physical and psychosocial development known as puberty.
In Stage 2, physical changes begin. Between the ages of 8 and 13, girls typically experience: Their breasts begin to bud, and their areolas (pigmented area around the nipple) enlarge. Scant pubic hair appears.
The breasts get bigger and rounder as the fatty tissue and milk-producing glands inside the breasts continue to grow. The areola also gets bigger and darker and the nipples may stick out. By the age of 17, a girl's breasts will usually be fully developed, although this may take a bit longer.
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.
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).
While your body is adjusting to all the new hormones, so is your mind. During puberty, you might feel confused or have strong emotions that you've never experienced before. You may feel anxious about how your changing body looks. You might feel overly sensitive or become easily upset.
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.
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.
As a girl approaches her teen years, the first visible signs of breast development begin. When the ovaries start to produce and release (secrete) estrogen, fat in the connective tissue starts to collect. This causes the breasts to enlarge.
Pubic hair – Once her pubic hair starts growing, you can expect her period to develop in one to two years.
Changes in Boys
They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
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.
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.
A breast bud is a lump that develops under the nipple in the first stage of breast growth. The lump may be tender and sore, but it is completely normal in girls undergoing puberty. However, if your child is under eight years old and developing breast buds, she may be experiencing precocious puberty.
