Kids start to have body odor around the time puberty starts and hormones change. Usually, this happens when females are 8–13 years old, and males are 9–14. But it can also be normal to start puberty earlier or later. Bathing every day, especially after a lot of sweating or in hot weather, can help with body odor.
Adrenarche is usually normal in girls who are at least 8 years old, and boys who are at least 9 years old. Even when pubic and underarm hair appear in children younger than this, it is still usually nothing to worry about, but your child does need to see their pediatrician for an exam.
The first sign of puberty for girls is breast development or breast budding. You may hear your doctor use a fancy term for this called thelarche. If you don't notice breast budding by the age of 13 you should be sure to have a check-up with your pediatrician or adolescent medicine doctor.
(We have not been able to find averages for other races.) On age alone: Age 15 1/2 to 16 1/2 for whites, age 14 1/2 to 15 1/2 for blacks. If no breast or hair development: Age 13 to 14 for whites, age 12 to 13 for blacks. If there is breast development or hair (pubic or armpit)two years after either of these started.

You can't prevent most early puberty cases. Limiting your child's exposure to reproductive hormones from outside sources may prevent it. These sources may include estrogen or testosterone creams, lotions or other medications.
Between the ages of 9 and 14: Breasts continue budding. Armpit (axillary) hair begins to grow and pubic hair continues to grow. Pubic hair is coarse, curly and forms in the shape of an upside-down triangle.
Results: Over a period of 18 months, 320 women from all over the world were included in the study (excluding women below the age of 18 years and double entries). The women's mean age was 34.1 years (±11.1) and their mean age at first ejaculation was 25.4 years. Most women ejaculate a few times a week.
Children with lower-nutrient diets tend to enter puberty earlier. A diet rich in processed foods and meats, dairy, and fast food is disruptive to normal physical development. Exposure to EDCs (endocrine-disrupting chemicals).
No mechanism evolved to shut off pre-pubertal and pubertal weight and body fat gain after puberty. The weight gain continues unabated throughout life.
There's no specific age for a child to start wearing deodorant or antiperspirant. Many start in their teens. Some start as soon as puberty starts to cause body odor, which can be as early 8 or 9 years old for some children. Then again, some never use it, even as adults.
Unlike getting a driver's license, there's no set age when girls decide they want to (or don't want to) start shaving their legs and underarms.
Shortly afterward, pubic and underarm hair begin to grow. In girls, puberty usually begins between the ages of 8 years and 13 years (see Puberty in Girls).
Conclusions. The reported data support the idea that vitamin D plays a key role as a regulator of neuroendocrine and ovarian physiology and that vitamin D deficiency contributes to altered pubertal timing.
Most girls get their first period when they're between 10 and 15 years old. The average age is 12, but every girl's body has its own schedule.
Emotional changes
Sometimes it will feel like a storm of emotions, ranging from irritability to sadness. Your daughter may experience confidence issues for the first time in her life. Emotions start to level out by the end of puberty. They may flair up around the time of your daughter's period.
As your child approaches puberty, everything changes. Your child's hormones are changing, which stimulates their glands and increases perspiration, especially in the underarm and groin areas. That increase in perspiration combines with the bacteria that live on the skin creating the odor.
Another common cause of delayed puberty in girls is lack of body fat. Being too thin can disrupt the normal process of puberty. This can occur in girls who: Are very active in sports, such as swimmers, runners, or dancers.
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.
Your periods will start when your body is ready. This is usually between age 8 and 17, or 2 years after your first signs of puberty.
Most girls get their periods somewhere between the ages of 9 and 16. But it's not unheard of for a girl's period to start before age 9. Rather than age, you can look for signals in your body. Most girls don't get their period until they weigh at least 100 pounds and have started developing breasts.
Leading up to your first period, you may notice these symptoms: Cramping (pain or achiness in your belly, back or legs). Bloating (your belly feels full or swollen). Tender or sore breasts (chest).
