Strictly speaking, 5 kg and 8 kg are not very healthy, and the birth weight of the fetus is the healthiest at 6 to 7 kg. Five catties and eight catties are on the edge of health. Children weighing 5 kg are too thin and prone to hypoplasia, especially in the heart, lungs and digestive system. The simplest performance is that it is very difficult for a child of 5 kg to suck milk, but he can't suck it out by himself and is easily choked by milk. Therefore, a child who fails to meet the standard will always stay in the incubator for a few days after birth.
The 8 kg newborn is a giant baby. First of all, it will be very difficult for women to give birth naturally, and there will be a risk of dystocia. So a fetal doctor of this weight will recommend caesarean section. Secondly, the probability of macrosomia getting diabetes, obesity, hypertension and other diseases in the future is greatly increased. Many old people will be complacent and show off everywhere when they see that their children are older than others. Everyone knows that the danger is behind. A child's weight does not mean that his body is healthier than others and his IQ is higher than others. On the contrary, overweight will affect bone development, resulting in slow height development, unbearable weight and heart overload.
More than 5 kg to 7 kg is the fetal weight within the standard range, suitable for parturient, and the fetus itself is in the best state. As for how to know the fetal weight, there is a formula: biparietal diameter × 900-5200. My child's birth weight is 200 grams less than calculated. Pretty accurate. In addition, doctors will also pay attention to the development of fetal weight in the late pregnancy, and even the weight will be directly displayed on the B-ultrasound list in the last two weeks.
Why do newborns have to be weighed at birth? In ancient times, a man wanted to drive his old mother away. The man said to his mother, "You raised me 20 years younger and I raised you 20 years older. Now we're even. We're even. Let's go our separate ways from now on. " "Listen to the man said, the old mother was heartbroken and wanted to die, just being seen by a passing magistrate.
When the magistrate learned about it, he took the man and his old mother back to the yamen to settle the case. In the court, the county magistrate asked the old mother how much her son weighed when he was born, and the old mother said 6 kg and 4 Liang. So the county magistrate pronounced that the man had raised his old mother for 20 years, and the time account had been paid off, but "the child is the meat that fell from his mother", so he had to pay this account ... The man turned pale with fear after hearing this, and never dared again. Indeed, "the child is the meat falling from the mother" is the happiest time for both mother and fetus in the days of integration. The weight of the newborn is not only meaningful to the baby, but also significant to the mother. Although this is a folk story, it shows that newborn weighing is very important.
The newborn's weight is an important index to measure the baby's health. Usually, the normal weight of a full-term baby is 2.5KG-4KG, and the male treasure will be heavier than the female treasure. Being underweight or overweight will have an impact on your baby's health. If it is serious, it will lead to patients with high blood pressure and diabetes when the baby grows up. Birth weight can also further track the baby's growth and development, judge whether the baby has developmental retardation, and find early treatment as soon as possible.
