Pubic hair begins to grow shortly after changes in the scrotum. At first it may be thin. It then gets darker and coarser. Boys also begin to grow hair in other new places, such as the chest, underarms, face, and legs about 2 years after the start of pubic hair growth.
This is most common in the later stages of puberty as the body begins to make sperm. Your child may be concerned that his peers are more or less developed than he is. Explain to your child that kids of the same age may be at different stages of puberty.
Help your child adjust to his changing body. Usually after a girl's 8th birthday or after a boy turns 9 or 10, puberty begins when an area of the brain called the hypothalamus starts to release gonadotropin-releasing hormone GnRH.
When GnRH travels to the pituitary gland a small gland under the brain that produces hormones that control other glands throughout the body , it releases two more puberty hormones — luteinizing hormone LH and follicle-stimulating hormone FSH.
At about the same time, the adrenal glands of both boys and girls begin to produce a group of hormones called adrenal androgens. These hormones stimulate the growth of pubic and underarm hair in both sexes. The physical changes of puberty for a boy usually start with enlargement of the testicles and sprouting of pubic hair, followed by a growth spurt between ages 10 and 16 — on average 1 to 2 years later than when girls start. His arms, legs, hands, and feet also grow faster than the rest of his body.
His body shape will begin to change as his shoulders broaden and he gains weight and muscle. A boy may become concerned if he notices tenderness or swelling under his nipples. But it usually disappears within 6 months or so. And that first crack in the voice is a sign that his voice is changing and will become deeper.
Dark, coarse, curly hair will also sprout just above his penis and on his scrotum, and later under his arms and in the beard area. His penis and testes will get larger, and erections, which a boy begins experiencing as an infant, will become more frequent. Ejaculation — the release of sperm-containing semen — will also occur. Many boys become concerned about their penis size. A boy may need reassurance, particularly if he tends to be a later developer and he compares himself with boys who are further along in puberty.
If a boy is circumcised, he may also have questions about the skin that covers the tip of an uncircumcised penis. Puberty generally starts earlier for girls, some time between 8 and 13 years of age. For most girls, the first evidence of puberty is breast development, but it can be the growth of pubic hair.
Pressing too hard on the razor could shave off some of the skin. Use extra care around the knees and ankles to avoid nicking the skin. Replace the razor or its blade often. A dull blade is more likely to tug, scrape and irritate the skin. Don't share razors. Sharing a razor can spread bacteria such as Staphylococcus aureus and cause skin infections. Electric razors. Some electric razors are designed specifically for girls.
These may be less likely to cut the skin, although they can still cause irritation. Some girls experience a small to moderate amount of clear or white vaginal discharge that starts about months before their first period.
This is a normal response to growing amounts of the hormone estrogen in the body. While timelines can vary, most girls get their first period within 2 — 3 years after the development of breast buds. The average age for girls to get their first period in the United States is around age It's important to emphasize that periods are a normal part of growing up.
Young girls should know that it's okay to talk about periods and ask questions about them. Some young people may have anxiety about how to handle their first period, given that it can happen unexpectedly. Providing supplies pads, tampons, and pantiliners for your child's locker or backpack and reviewing resources at school, including the school nurse, can help alleviate this worry.
While some people will have periods once a month, periods may be irregular in the first few years as the body adapts to rapid physiological changes. Also, normal cycles of periods can be as short as 21 days or as long as 35… so even people with regular cycles might not have a period every single month!
Abdominal cramping or pain with periods is also common. For most people, ibuprofen or naproxen used as needed are the best medicines to help with period cramps. If menstrual cramps are severe or causing your child to miss school, talk to your pediatrician about other options. Most girls have their growth spurt at a younger age than boys do. The fastest rate of height growth usually occurs in girls between when breast buds start to develop and about 6 months before they get their period.
Once a girl has had her first period, her growth has already started to slow down. Most girls grow another inches after getting their period, but increased height beyond that is less common. Many young people develop acne during puberty. This can be related to changes in hormone levels during this time. With more oil and sweat being made by the skin, girls this age may start wanting to shower or shampoo their hair more often.
On occasion, girls start puberty either very early or very late. Contact your pediatrician if you begin to see pubertal changes before your daughter is age 8. Likewise, contact your pediatrician if there are no pubertal changes in your daughter by age There is some debate on this. The short answer to this question: maybe. It's clear that the starting age for puberty has decreased over the last years, likely related to improved nutrition.
