TV plays often say: “Congratulations, XX, have a big fat boy!” But in real life, the fatter the baby, the better? From a scientific point of view, this is not the case. A child’s birth weight in a certain range is a sign of good health. < / P > < p > when JUANJUAN’s mother-in-law knew that she was pregnant, in order to make her child develop better, she made all kinds of soup stews for JUANJUAN every day. She hoped that she would have a fat boy and be more blessed in the future. < / P > < p > under the feeding of her mother-in-law, Juan Juan’s stomach became bigger and bigger, and her weight soared sharply. When she went to the prenatal examination last time, the doctor said that the fetus was seriously overweight. According to this situation, it is very likely that the fetus will have a “giant baby” during production. < / P > < p > and the mother-in-law on one side laughed and said, “this is good. The heavier the baby, the smarter it is.” Did not expect mother-in-law just finished this sentence, was severely reprimanded by the doctor. < / P > < p > at this time, the mother-in-law knew that the weight of the fetus had nothing to do with the IQ, overweight, dystocia at birth, obesity and other diseases after birth were very likely. < / P > < p > the doctor pointed out: the baby’s birth weight is between 5-8 Jin, which is normal. If it is less than 5 jin, the brain development may be incomplete due to too light weight, which will affect its intellectual development; if it is more than 8 Jin, the baby’s weight will exceed the standard, and the risk of illness will be greatly increased after birth. < / P > < p > of course, because the development of each fetus is different, there will be differences in birth weight. Some babies can’t reach 6.5 kg, but it can’t be said that they are not smart. 6.5 kg is just a reference value, not absolute. < / P > < p > overweight babies, because of over nutrition and too much weight after birth, will bring a special burden to the respiratory system and digestive system, especially the heart, and are more likely to get sick. < / P > < p > if the pregnant mother supplements too little folic acid and vitamin A during pregnancy, it will lead to fetal malnutrition, and the probability of premature, low weight and abnormal infants is very high. < / P > < p > if pregnant mothers often eat big fish and meat or overeat during pregnancy, it will lead to over nutrition, easily make the fetal weight exceed the normal range, and increase the probability of dystocia. < p > < p > many pregnant mothers stay at home all day after pregnancy, and do not exercise, but in fact, if pregnant mothers can do exercise during pregnancy, such as walking more, doing yoga, right It’s good for you and the baby. < / P > < p > reasonable exercise can help pregnant mother’s body absorb better, improve physical fitness, lay a good physical foundation for the next delivery, control fetal weight and promote brain development. < / P > < p > pregnant mother’s mood will greatly affect the development of the fetus. If pregnant mother is often in a bad mood during pregnancy, it will easily lead to fetal malformation and premature delivery. If the pregnant mother’s mood is happy, then the fetus will be affected by the pregnant mother’s mood, and the growth and development will be faster. < / P > < p > excessive use of electronic products by pregnant women during pregnancy may affect the normal rest time of pregnant women on the one hand, and on the other hand, the radiation of electronic products is high, so long-term use of electronic products by pregnant women will increase the possibility of fetal malformation. 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!
