Many new pregnant mothers who are pregnant for the first time have no experience in giving birth to their children. They all rely on the experience of the older generation. However, some of the past statements are no longer popular in modern society, and blindly listening to them may bring some adverse consequences. Xiaoxiao got pregnant soon after she married her husband. The family were very happy. Because Xiaoxiao was the first child and she was too young to understand anything, her mother-in-law volunteered to take care of her from her hometown. < / P > < p > in order to ensure the healthy growth of the fetus in Xiaoxiao’s stomach, her mother-in-law changes patterns every day to make delicious food for her, saying that she must eat more, so that the baby can grow fat. < p > < p > in the old people’s view, when a child is born, he will be blessed if he grows fat and white, and the stronger he is, the better he will be. At this time, Xiaoxiao will eat two supplements for one person, so it is best to eat more. < p > < p > although Xiaoxiao refused to look at the large amount of meat and tonic soup, it was not against the old man’s meaning to think that the children in her stomach needed nutrition, so every meal was clean. < p > < p > but when Xiaoxiao went to have a prenatal examination in the third trimester of pregnancy, the results showed that her blood lipid and blood sugar were high, and the fetus was a little too large, so it might be difficult to have a natural birth. After hearing this, Xiaoxiao was shocked, and her mother-in-law said that she couldn’t believe it. After detailed understanding, the doctor told them that it was not advisable to take large-scale supplements during pregnancy, which would not only easily lead to fetal malnutrition, but also be harmful to the health of pregnant mothers. There is no scientific basis for mother-in-law Xiaoxiao’s saying that the fatter the fetus is at birth, the more blessed she is. Don’t listen to these “rumors” and make up for it, otherwise the consequences will be unimaginable. < / P > < p > at that time, the living conditions were poor, many pregnant women were also lack of nutritional supplement during pregnancy, they may need to work to maintain their livelihood, and they can hardly get a good rest. < p > < p > therefore, the nutrition of the child is relatively poor, and the weight is naturally lighter. On the contrary, if the family conditions are good, the pregnant mother does not need to work hard during pregnancy, and can supplement enough nutrition, so the growth and development of the fetus will be guaranteed. However, with the continuous improvement of the economic level, pregnant mothers can basically get better care during pregnancy, and there will be no situation that their nutrition can not keep up with it. This view has gradually been eliminated. < p > < p > under normal circumstances, newborn babies can be divided into three grades according to their weight. The normal weight is about 5-8 kg. If the weight is more than 8 kg, it belongs to “macrosomia” and may face cesarean section. If the weight is less than 5 kg, the fetus is too small and dysplasia. However, recently, a new best weight standard for newborns has been published, which is mainly measured by three indicators. The babies who meet the requirements tend to be healthier and have better intellectual development. < / P > < p > if the baby’s birth weight is between 5 and 8 Jin, and the baby’s crying is loud and the grasping ability is strong, then it shows that the intrauterine nutrition is sufficient, the baby’s congenital quality is good and the intellectual development is good outstanding. If the birth weight is less than 5 jin, and breathing is weak, it indicates malnutrition and immature body development. 3. Maternal quality < / P > < p > if there are blood sugar problems or heart problems, it may be easy to give birth to low birth weight infants. On the contrary, the mother with good health often gives birth to a baby with normal weight. < / P > < p > many pregnant mothers have poor appetite during pregnancy and want to eat some sour and sweet food to help appetizer and improve their appetite, so fruit has become their best choice. Although most fruits are rich in vitamins, dietary fiber and minerals, they also contain a lot of sugar. A large amount of intake during pregnancy can easily lead to high blood sugar in the body, which is not conducive to their own and fetal health. < p > < p > during pregnancy, the food should be light, avoid frying, frying, barbecue, and other cooking methods, such as frying, boiling, boiling and stewing, which can not only avoid nutrient loss of food materials, but also reduce the intake of fat and fat. < / P > < p > especially for the production of meat and other meat dishes, after all, these contain a lot of fat, which will increase the fat content after cooking by frying and other methods, which can promote the weight growth of pregnant mothers and fetuses. Although pregnant mothers should avoid strenuous exercise during pregnancy, they can do some gentle and soothing aerobic exercises, such as walking, aerobic yoga and gymnastics. < p > < p > daily exercise for about half an hour can promote digestion, help control body weight, prevent body weight and fetal weight from growing too fast, and it is also conducive to normal labor. < p > < p > generally speaking, it is normal to control the weight gain between 23 and 32 Jin during the whole pregnancy. Pregnant mothers can reasonably distribute the weight and increase according to the corresponding indicators in each stage to prevent the weight gain too fast. < / P > < p > although the fetus in the mother’s stomach, need to rely on the mother’s diet to absorb nutrition, but we should also pay attention not to take large amounts of supplements. One person can eat two people’s meals. < p > < p > pregnant mothers must pay attention to reasonable diet during pregnancy, according to the standard of high protein and low fat, in order to control their own and fetal weight in a reasonable range. After pregnancy, do not let the wife do these five kinds of housework, the husband should be responsible for it, otherwise it is easy to hurt the fetus!
