Calculation method of birth of boys and girls

China is the crystallization of 5,000 years of traditional wisdom. Since ancient times, because everyone is curious about the sex of the fetus, many magical methods have been produced to test the sex of the fetus. So, what about having boys and girls? How to test these methods? How to make a budget? Is the method accurate?

Calculation method of birth of boys and girls

First, we can call it seven seven forty-nine, then ask the pregnant woman when she will give birth (the lunar month when she is pregnant), then subtract the mother's age (the imaginary age when she is pregnant), add 15, and then subtract 1, 2, 3, 4, 5, 6, 7 one by one, and so on until we get a number. Boys use singular numbers and girls use even numbers. The calculation method is: 49+ the lunar month when the mother is pregnant-MINUS the imaginary age of the mother+19=, and the mantissa is single, which is a boy; The mantissa is double. It is a girl. For example, when the mother is pregnant, she is 28 years old, and when she is pregnant, she is in August of the lunar calendar. The calculation method of giving birth to boys and girls is 49+8-28+ 19=48, and the mantissa is double, which means giving birth to girls. 20 17 children's palace clearance map is not necessarily reliable. There is no scientific basis for people to know the products caused by fetal sex in advance. Young couples can use the above prediction table 20 17 to predict the birth of boys and girls in their spare time. At present, the most accurate way to know scientifically in advance whether to have a boy or a girl is to do B-ultrasound, amniocentesis or blood sampling to detect DNA. However, it should be noted that the determination of fetal sex is to prevent the occurrence of sex-linked genetic diseases and achieve the purpose of prenatal and postnatal care. Under normal circumstances, doctors will not give pregnant women a sex test. In fact, boys and girls are all the same. The key is that children are healthy and smart.

Precautions for male baby to take a bath

Control the water temperature: the external genitalia of the baby boy is the place where his whole body temperature is low, and it is also the place where he is most afraid of heat. The temperature of the water used to wash the genitals of male babies should be controlled within 40℃ to avoid scalding the baby's delicate skin. In fact, the most ideal temperature is about 37℃ which is closest to the baby's body temperature. Don't use force: the baby's external genitalia is covered with nerve tissue, and the skin is very fragile. You need special attention. The technique should be light, steady and soft to avoid squeezing or pinching the baby's external genitalia, including penis and scrotum, because of temporary tension. Avoid excessive stimulation: the baby's external genitalia will expand when heated, and the urethral orifice will open. Excessive stimulation may increase the chance of baby's urinary system infection. Some experts also believe that excessive stimulation of the baby's external genitalia will stimulate the baby's sexual orientation and increase the risk of precocious puberty. Cleaning: gently lift the baby's penis and gently dip the roots with soft gauze. Then clean the baby's scrotum, where there are many folds and it is easier to hide sweat. The lower part of the scrotum is also a place where sweat and dirt are easily hidden, including near the groin, which should be wiped with emphasis.
