Our body's little secrets

The development of breasts is the first sign of puberty for girls. What changes will occur? At first, you will feel a little swelling and pain in your breasts. When you touch them, it feels like a small lump. Breasts will grow and change shape over time. Slowly, you will find that the color of nipples will gradually darken as they grow.

Have you also found that not all girls of your age have changed in the same way as you? Don't worry, that's because the time of breast development of girls is not exactly the same. They are affected by various factors such as hormone levels, nutritional intake, genetic genes, etc. Generally speaking, the age of breast development of girls is between 9 and 13 years old.

1. Choose a suitable bra <br /> When you find that your breasts are beginning to develop, don't worry or be shy, and don't lower your head or walk with a hunched back because of shyness. This is a sign of your growth, a normal natural law, and a process that every girl will go through. At this time, what do you need to do? Tell your mother the little secrets of your body changes, and with her help, choose a suitable bra for your slowly developing breasts. In the early stages of breast development, a vest-style bra is most suitable for you, as it can gently support your chest and protect your privacy. There is nothing to be embarrassed about.

Tips: Before choosing bras, you need to know how big your bust is. You can use a tape measure to measure horizontally from under the armpits through the two nipples.

2. Some problems you may encounter
1. The size and shape of girls' breasts vary. Due to the uneven development of the breasts on both sides, sometimes one side is slightly larger and the other is slightly smaller. This is normal and there is no need to worry too much.

2. Sometimes we feel some slight pain in the breasts, which is a sign of their growth. Of course, before the menstrual cycle every month, the breasts will also experience varying degrees of pain, which is normal. However, when the pain is unbearable, or the surface of the breasts is obviously red or hot, you should seek help from your parents or doctors in time.

3. Usually we feel a small lump in the newly developed breast, which is normal. As the breast develops and the mammary gland grows, the lump will gradually disappear. If the lump does not disappear and there are abnormalities such as redness and swelling, you should tell your parents in time and it is best to go to the hospital for examination.
