What to do if a 9-year-old girl has breast development

We all know that girls develop earlier than boys. Many girls start to develop breasts when they are eight or nine years old. Therefore, it is normal for nine-year-old girls to develop breasts. Parents don’t need to worry. At this time, they only need to teach them some knowledge about girls’ development, buy them underwear that suits them, and teach them some hygiene knowledge.

1When does breast development begin in girls?

Normally, the average age of breast development for girls is 10.8 to 11.4 years old. If parents find that their children are developing breasts at a rate that is inconsistent with the normal age of puberty, they must pay attention to it. The phenomena of normal breast development are as follows:

1. Girls' breast development usually starts when their nipples begin to grow, and the age of breast development is around 9 to 10 years old.

2. Girls will experience breast hyperplasia when they reach the age of 10 to 11. At this time, a breast nucleus will be formed. When you touch it with your hand, you will find a nodule or a small lump, and it will also feel tender.

3. When girls reach the age of 12 to 13, the mammary ducts and subcutaneous fat will slowly increase, the breasts will gradually swell and become elastic, and at this time, the color of the areola and nipples will gradually become darker.

4. The mature breasts of girls are shaped like a basketball and are usually located between the 3rd to 6th ribs. The nipples also have the function of erection. They will become hard when touched, which is conducive to breastfeeding.

2 There are so many reasons for early breast development

1. Nutritional improvement

Today's family living conditions have become better, nutrition has improved, diseases have decreased, and children's growth and development have accelerated, leading to earlier sexual development and an increase in sexual maturity.

2. Environmental pollution

Industrial pollution is increasing in today's society, and food also contains a large amount of pesticide or hormone pollution. These pollutant residues, after passing through the skin or directly eaten, are a cause of precocious puberty in children.

3. Foods containing hormones

Many vegetables and poultry nowadays contain large amounts of hormones. Some sex hormones can indirectly enter the human body and cause precocious puberty in children.

4. Blindly taking supplements

"Supplements are one of the main causes of precocious puberty in children." Some parents often give their children health supplements that increase appetite, improve intelligence and strengthen the brain. Little do they know that these supplements often contain hormone ingredients. Long-term use can cause the hormone level in children's blood to rise, thus leading to precocious puberty in children.

3 What to do if a nine-year-old girl has breast development

With the development of economy, puberty is getting earlier and earlier. There are many factors that affect children's development, mainly race and genetics, but climate, nutrition, and disease also play a big role. Therefore, there are great individual differences in children's development. Nowadays, girls generally start to develop at the age of 8 to 8.5 years old, and usually get their first period between the ages of 11 and 18 years old.

Girls' breast development usually begins when their nipples begin to grow, around the age of 9-10 years old. When the age of 10-11 years old, the breast hyperplasia forms a breast nucleus, which feels like a nodule or a small lump and is painful when pressed. At the age of 12-13, the mammary ducts and subcutaneous fat increase, the breasts gradually become firm and elastic, and the color of the areola and nipples becomes darker. The mature breast is blue and spherical in shape and is located between the 3rd to 6th ribs. The nipples have an erectile function and become hard when touched, which is conducive to breastfeeding.

Girls enter puberty at around age 12. Due to the stimulation of endocrine hormones, their breasts begin to develop, and the milk ducts and alveoli proliferate. The development is completed at around age 16, and generally no longer increases after age 25. After the breasts mature, their size and shape often vary from person to person. The size of the breasts is mainly determined by the fat content. People with thin bodies have flatter breasts, while obese people have fuller breasts. Breasts can be pear-shaped or disc-shaped.
