Girls grow up to 16 to 18 years old, and the development of breast corridors and breasts is close to maturity. Use a soft ruler to measure from the bottom of the breast through the nipple to the bottom of the breast. When the distance between the top and bottom is greater than 16cm, you should wear a bra.
The size of the bra should be moderate. 二次發育If it is too small, it will compress the breasts and nipples and affect the breathing and the development of the rib cage and breasts. If a bra is too large, it will not support and protect the breasts. The bra should be taken off when sleeping to avoid affecting breathing and blood circulation.
After the girl is 14 years old, pubic hair gradually develops. I can observe the distribution of fine hairs growing on the skin of the pubic caruncle, but this is not the real pubic hair. The real growth of pubic hair needs to go through sparse, light-colored pubic hair, until it gradually becomes darker, thicker and curled, and from a small amount of distribution to a relatively dense distribution, before it reaches the distribution state of adult female pubic hair. 二次發育The typical adult female pubic hair is distributed in an inverted triangle shape.
Most girls have menarche, usually between thirteen and fifteen years old, but some people appear earlier, perhaps at the age of eleven to twelve, and may appear late at the age of eighteen to nineteen.
The girl herself will feel that her menstrual period has changed from irregular to normal. The menstrual cycle is generally irregular in the first year after menarche, and generally does not ovulate. In the second year, the menstrual cycle is normal, and ovulation is possible in every cycle.
What do girls eat for development?
During the developmental period, girls should add more nutrition and drink more milk. Milk is rich in protein and calcium, which can promote the development of bones and promote the development of breasts, so that girls’ breasts are plump and straight.
Girls can eat more papaya and milk during development, which will help breast growth. pay attention to eating more vegetables to supplement vitamins. In addition, girls can properly supplement blood, such as stewing snow swallows.
Adolescent girls have a greater need for calories. They need 2600-2700 calories a day, which is more than adults. These calories mainly come from sugar, fat and protein. And some people do not eat breakfast or are not full, and the supply of calories is obviously insufficient, which will affect growth and development, so breakfast must be eaten well.
Adolescence has a considerable need for protein, minerals, and water, and it needs to be comprehensive. Women’s protein needs are about 80-90 g/day. The composition of protein in different foods, that is, the types of amino acids are not the same, so you should eat a variety of foods to make the supplement of amino acids comprehensive and not picky eaters.
