Why is it said that the birth of a girl is delayed, and is it easy to give birth to a girl due date?

Boys are also born earlier than girls. Male babies are generally better than due dates.

Babies will have to give birth a few days later than their due date or on their due date. A lot of moms don't quite understand this.

1.Babies born between 37 and 42 weeks are considered full-term, which is relatively normal. But in summary, boys are born much earlier than girls, with only one girl out of every 18 babies born earlier than their due date.

And why is it that a baby girl is born so late than a boy? This is mainly due to a gene in the body of the baby boy. This gene causes boys to have a higher elimination rate than girls, and also makes boys more likely to be born prematurely than girls.

2.Boys are more active than girls. Boys always like to punch and kick in their mother's belly, while girls are relatively quiet.

The boy baby moves in the womb in this way, which leads to the male baby entering the pot earlier than the female baby, and the birth time will naturally be earlier, while the female baby will give birth much later.

3.Hormones are different. Male babies have male hormones in their bodies.

More, estrogen in the body of the baby girl.

Many. Male babies tend to be precocious due to hormones, so boys are born some time earlier than girls, while girls tend to be born later.

However, these are folk sayings, parents should not believe too much, no matter whether the baby is born male or female, the mother should take care of the baby and let the baby grow up healthily.

Precautions for first-trimester care:

1. No contact with tobacco and alcohol: Not touching tobacco and alcohol not only means that you do not smoke or drink, but also include not staying in a smoking environment for a long time, and passive smoking will also cause harm to children.

2. Brush your teeth frequently: due to morning sickness.

Reaction, expectant mothers need to brush their teeth frequently to avoid their teeth being destroyed by vomiting residue; In addition, expectant mothers who have just become pregnant like to eat sour foods, which are the most likely to spoil their teeth.

3. Coping with vomiting: If the expectant mother always wants to vomit after eating, then she needs to prepare a towel and mouthwash with her.

If the expectant mother hasn't told her boss and co-workers about her pregnancy, then she should come up with a convincing excuse in case the co-worker helps you when you're not feeling well.

4. Appetite when you lose your appetite: In addition to the taboo foods that pregnant women eat, they can eat whatever they like. Generally early pregnancy.

of expectant mothers like to eat acidic foods such as oranges, dried plums or kimchi. Therefore, husbands and family members should prepare more of these foods. Because the fetus grows slowly during the first trimester, it doesn't need much nutrition.

5. Eat small meals often: eat every 2-3 hours. In order to reduce the morning sickness reaction, you can eat more dry foods, such as baked cakes, biscuits, baked steamed bread slices, bread slices, etc.

If the expectant mother has severe morning sickness, she should pay attention to eating more alkaline foods such as vegetables and fruits to prevent acidosis.

It is said that boys are naughty and girls are quiet.

Therefore, the quiet girls are all ashamed to answer, and they dare not come out in their mother's belly.

Not necessarily, conceiving a girl may delay birth.

The due date is the expected date of delivery, not the exact date of delivery, and scientists have calculated that only about 5% of women give birth on the due date. According to some foreign surveys and studies, it is true that the baby boy will be more likely to report in advance. Experts believe that this is because the hormones secreted by pregnant mothers are different when they are pregnant with a baby boy and a baby girl.

Conversely, the birth of a baby girl is often delayed after the due date, so the birth of a girl may be delayed.

Girls are slightly more likely to postpone birth.

Since the expected date of delivery is used as a comparison, and the expected date of delivery is a unified algorithm, let's ignore some special circumstances and take a look at the conclusions of foreign research. Although there are not many clinical research data in China, there are many large sample studies in Europe and the United States that support the conclusion that whether it is in preterm infants (babies born at 28 weeks and less than 37 weeks) or full-term infants (born at 37 weeks to 42 weeks), the shorter the mother's gestation, the higher the proportion of male babies born.

A Norwegian study analysed birth data from about 1.7 million babies born between 1967 and 1988 and found that the ratio of full-term babies born earlier than the expected date (40 weeks) was 10 weeks; Babies born after the due date are equal for men and women.

In France, a larger population study found that the proportion of male fetuses born in both preterm and full-term babies decreased with the number of weeks of gestation. Moreover, this trend is ethnically specific, and it is very obvious in the white population, but this pattern is not found in the black population. However, the small sample size of blacks collected in this study may also lead to statistical discrepancies.

Only some studies on preterm infants in China have found that the proportion of male infants in preterm infants is significantly higher than that of female infants, and there is no reliable data analysis for term infants. If we really want to find out whether our Chinese babies also have such a trend, we have to wait for the results of a large sample of domestic population.

From the statistics, we can see that the "early birth of a noble son" has a certain amount of truth in terms of statistical probability.

Judging from the life experience of the elderly, if they conceive a girl, they will be born a few days later than the expected date of delivery. This is a matter of probability, and it cannot be counted as a basis for judging the sex of the fetus when it comes to the individual. When the due date arrives, the reason why the due date has not yet been born is that there is an error in the calculation of the due date.

1.Alpha-fetoprotein is high. High alpha-fetoprotein will directly lead to the postponement of the expected date of delivery of pregnant women, pregnant women must be directly checked at 14 weeks to 29 weeks to check whether this element is high, if it continues to be high, then it is likely that the due date is wrong.

2.Irregular menstruation. If a pregnant woman has irregular menstruation before she becomes pregnant, it is difficult to accurately calculate the due date. After all, the calculation of the expected date of delivery is based on the menstrual cycle, and the calculation of the due date cannot be particularly accurate if the menstrual cramps are not accurate.

The inspection time is not correct. B-ultrasound examination is the content of the prenatal examination that must be done by pregnant women during pregnancy, and the fetus will be larger when B-ultrasound is done later, so the estimated date of delivery will not be particularly accurate. Therefore, expectant mothers with irregular menstruation should remember to do it at the right time.

Dietary considerations in the third trimester.

In the third trimester, expectant mothers enter the final sprint stage, and the storage of nutrients is particularly important for expectant mothers. A safe, healthy and reasonable diet is a necessary prerequisite for the healthy birth of a fetus. Combined with the nutritional characteristics of the third trimester, the diet of the second trimester should be adjusted accordingly.

1. Diversified dietary requirements: In the late stage of pregnancy, expectant mothers not only need to supplement calories, but also pay attention to the supplement of nutrients such as high-quality protein, iron, calcium and vitamins, and can adopt a diet of eating less and more often, which can increase to more than 5 meals a day. Do not take a large amount of supplements to avoid excessive obesity and macrosomia (the weight gain of expectant mothers during pregnancy should not exceed 15 kg).

2. Supplement sufficient calcium and iron to help the fetus's teeth and bones calcify well and prevent anemia of expectant mothers, you can eat more kelp, seaweed, dried shrimp, sesame, animal liver, eggs, fish, etc.

3. Increase the intake of plant-based proteins, such as beans and soy products.

4. Reduce the intake of foods with high sugar content, such as fruits, sugar, honey, etc., so as not to overgrow the fetus and affect the smooth delivery.

5. Eat more foods with high nutritional value and small size, such as animal foods; Eat less foods with low nutritional value and large volumes, such as potatoes, sweet potatoes, etc.

This is based on the individual's constitution, and it does not mean that the due date of giving birth to a girl will be delayed.
