Is it normal for 7 year old to have pubic hair
We all know that boys and girls develop at varying rates. Generally girls develop faster and sooner than boys do. There is actually a pattern that each gender follows in their development, pubic hair being one of the first signs of beginning puberty. Girls start puberty between the ages of The beginnings of puberty are initiated by the pituitary gland which produces and send hormones coursing through their body for the first time.
These hormones cause their bodies to change and develop, causing them to look more like women than little girls. The first thing they will notice is pubic hair, body odor, and the beginning development of their breasts. Her brain is starting to develop rather quickly at this point. Boys start developing at around age The pituitary gland also sends hormones, but the hormone that is sent is different than for girls. Testosterone begins to be released and the male organs begin to develop.
Along with the beginnings of male organ development, a boys will start to grow pubic hair and body odor. They can also start having wet dreams which are dreams of sexual arousal that cause them to ejaculate in their sleep. Note : This is perfectly normal even though it might be uncomfortable and embarrassing for your growing boy. They also develop armpit hair, have a growth spurt, and their penis and testicles will grow. All are part of puberty and are completely normal. This all happens between the ages of and is a gradual process.
The smallest changes come first and gradually get faster and more extreme the deeper into puberty the boy goes. Precocious or early puberty is when your child starts developing before they reach the normal developmental age. Precocious puberty can be a cause for concern. If your young child has signs of puberty, it might be a wise idea to have a check-up to rule out this condition. However, over the past few decades, onset of puberty has gotten earlier than in the past. There are 2 different types of precocious puberty; Central precocious puberty and peripheral precocious puberty.
This is caused by the premature secretion of gonadotropins from the brain. The release can be caused by:. While these are all causes, the list is still uncertain. The currently approved hormone treatment is with drugs called LHRH analogs.
These synthetic man-made hormones block the body's production of the sex hormones that cause early puberty. Positive results usually are seen within a year of starting treatment. LHRH analogs are generally safe and usually cause no side effects in kids.
In girls, breast size may decrease. In boys, the penis and testicles may shrink back to the size expected for their age. Growth in height will also slow down to a rate expected for kids before puberty.
A child's behavior usually becomes more age-appropriate too. Give your child a simple, truthful explanation about what's happening. Explain that these changes are normal for older kids and teens, but that his or her body started developing a little too early.
Keep your child informed about treatment and what to expect along the way. Also watch for signs that teasing or other problems may be affecting your child emotionally. Common warning signs to discuss with your doctor include:.
How parents react can affect how well kids cope. To promote a healthy body image and strong self-esteem :. The important thing is that doctors can treat precocious puberty.
They can help kids keep their adult height potential and limit the emotional and social stress kids may face from maturing early. Pediatrics : 61 — Pediatrics 99 : — Thamdrup E Precocious sexual development: a clinical study of patients.
