Girls are easier to observe. Generally, if there is a bulge in the breast, it may be that puberty development has begun. If a boy's voice changes and even grows a beard, it's too late. The development of boys often begins with the enlargement of testicles. If a boy's testicles grow bigger than pigeon eggs's, it should be the beginning of the boy's development.

Because the early performance of sexual development is not obvious, and the children themselves are not very clear. All this depends on parents' careful and frequent observation, timely detection and early treatment. Therefore, same-sex parents can check their children's secondary sexual characteristics at the same time every month, such as mothers checking their daughters' breasts and fathers observing their sons' testicles. Sometimes, some children's sexual development may begin with the appearance of body hair. If the child is found to be under the age of development during routine examination and the above situation occurs again, it is necessary to go to the hospital to find a special child endocrinologist for treatment. Some children with precocious puberty may start before they are five or even four years old, so routine examinations can't be carried out until after primary school, but the earlier they start, the sooner they form habits, the better.

Precocious puberty may not only cause children's psychological inferiority, but also make them feel different from other children. At the same time, the final height is affected by premature development. Some abnormal precocious puberty may even be a sign of some tumors. Dear parents, from now on, always pay attention to the development of children.

Experts pointed out that parents should give their children the following common "high hormone" foods as little as possible:

1. Poultry Neck At present, most poultry are "ripening", and the residue of "ripening agent" in poultry meat is mainly concentrated in the glands of the head and neck of poultry. Therefore, eating the necks of chickens, ducks and geese for a long time has become a high-risk behavior of "promoting precocious puberty".

2. Out-of-season fruits such as strawberries, watermelons, grapes and tomatoes. In winter, pears, apples, peaches and oranges. Almost all those listed in advance in late spring are out of season or mature in advance with the help of "ripening agent", so we should also avoid giving them to children.

3. The high calorie of fried food will be converted into excess fat in children, causing endocrine disorders and leading to precocious puberty; Moreover, after repeated heating and use, high temperature makes it oxidized and denatured, which is also one of the reasons for "precocious puberty".

4. Oral nutrient solution Some oral liquids contain hormones. After taking it, children grow taller and stronger than their peers at the age of five or six. Children will not grow up when they enter the normal development stage. Therefore, we should not blindly buy oral rehydration for children in the market.

5. Tonics There are many brands of colostrum on the market, which promote improving the immunity of infants and young children. Many mothers who care about their children buy them. In fact, colostrum is the milk of a cow's mother who just gave birth to a heifer in the first week. The content of gonadotropin in colostrum is extremely high, which may not be a problem for infants, but for children close to puberty, the body is more sensitive, and it is easy to enter puberty early after long-term and large-scale use.

6. Improper method of cooking soup If the soup is cooked with animal viscera, substances containing hormones such as thyroid gland and gonad will precipitate and be ingested into the human body through meals. Therefore, to make soup for children, we should put less animal offal.
