It is well known that multiple births, including twins, are good, especially twins, so I won't go into details here.
But the "bad" of twins is not known to most people, so I will focus on it here.
Include two aspects:
The "bad" nature of multiple births;
The unique "bad" of "twins"
First of all, the benefits of multiple births, including twins, come at the expense of mothers and babies taking more extra risks than singletons.
The risks of multiple pregnancies to mothers include:
Pregnancy-induced hypertension increases the risk of preeclampsia;
Increase the risk of gestational diabetes; The risk of diabetes after childbirth will also increase. Gestational diabetes will also increase the risk of neonatal respiratory disorders and hypoglycemia;
Increase the chances of dystocia and caesarean section;
It also increases the risk of postpartum depression.
The risks of multiple pregnancies to the fetus include:
Affect fetal growth. Multiple births are usually more prone to growth and development problems than singletons. Including low weight, especially inconsistent development, that is, one fetus is significantly smaller than other fetuses;
Affect the accuracy of genetic disease screening test results. It is known that prenatal screening can find many genetic developmental defects in advance, thus avoiding the birth of babies with severe developmental defects. In multiple pregnancies, the accuracy of the test results will be affected due to the interference of sample collection;
Twin transfusion syndrome. For single chorionic-double amniotic twins, twin transfusion syndrome may occur, that is, the blood supply between the two fetuses is unbalanced, and one fetus "steals" the blood of the other fetus, resulting in unbalanced development and injury;
Premature delivery. Premature delivery is the most common complication of multiple pregnancy. More than half of twins are premature, and it is often difficult to avoid premature delivery in triplet and above pregnancies. We know that premature babies, especially those born before 37 weeks of pregnancy, may increase the risk of short-term and long-term health problems, including breathing, eating and keeping warm. And long-term problems such as learning and behavior disorders, as well as the risk of certain diseases in adulthood. Even with the best medical care, very early premature babies (babies born before 32 weeks of pregnancy) will greatly increase the risk of death or serious health problems.
The risk of cerebral palsy increases. Cerebral palsy (CP) is a serious complication caused by perinatal fetal brain injury, which is more likely to occur in multiple pregnancies, especially premature delivery.
In addition to the "bad" nature of multiple births, the twins have a special disadvantage, that is, the "Phoenix" among them faces extra fetal development, many defects and weak performance of life after birth.
For a long time, girls have been observed to have some adverse effects in the twin model.
The explanation for this phenomenon is that when twins develop together in the uterus, female fetuses will be exposed to male hormones, which will cause some adverse effects, not only affecting the development in the uterus, but also affecting the developmental defects after birth and even life. This theory is called "twin testosterone transfer hypothesis".
Call it a hypothesis, that is, more evidence is needed to prove it.
A new study in Sweden, which is also the largest study in this field so far, has further explored this.
In this study, researchers recorded and analyzed the data of 13800 Norwegian twins born between 1967 and 1978.
The results show that, compared with other types of twins, women in twins show several disadvantages during the follow-up period of more than 30 years.
For example, their probability of finishing high school is low 15%, and their probability of finishing college is nearly 4%.
Their lifetime fertility rate is 6% lower, and the possibility of marriage is almost reduced 12%.
The economic income is also significantly lower than the average level of social women and 8.6% lower than that of female twins.
These differences still exist even if the boy of twins dies shortly after birth. This also means that this difference is not caused by the difference of parenting style after birth caused by parents' preference for sons over daughters, but more likely to be caused by congenital differences, that is, the exposure of androgen in uterus.
To sum up, it can be seen that although multiple births, including twins, often bring people a feeling of joy and good luck, these "good" also come at a price.
Of course, these "costs" are not enough to guide and influence people's reproductive choices, especially in the case of naturally forming twins or multiple births, because naturally occurring multiple births are inevitable.
However, with the wide application of assisted reproductive technology, including ovulation induction drugs and IVF technology, people can really choose multiple pregnancies on their own initiative.
In fact, in the past 30 years, the number of multiple pregnancies in the world has generally increased several times.
When you want to choose multiple pregnancies through assisted reproductive technology, you still need to think carefully. You should not only see its "good" side, but also clearly realize that there are many "bad" sides.
My family is twins, an elder sister and a younger brother.
Generally speaking, twins are a rare blessing.
There are many good aspects:
1, kill two birds with one stone. Some depend on genetic inheritance and the tradition of whether the family has twins; Some need to rely on technology, such as ovulation induction or monitoring. It is very good for mom and family to do two things at a time, so that Ma Bao won't have to suffer a second time.
2. Two small conjectures. For children, having the closest playmates since childhood is of great benefit to their development and growth. For a one-child family, sometimes it is more convenient to think about going out to play with other children every day.
3. Sanyang Kaitai. Mainly refers to the mother's love for children, the father's love for children, and the sister's love for the younger brother or the younger brother's love for the older sister. I always think that a family with two big and two small, two men and two women, and two "good" characters is the most complete, which is the greatest wealth of the family.
The bad side, in fact, is nothing compared with the good side, it is a trivial matter.
1, fiscal deficit. The cost of two is definitely higher than that of one. It started from the womb, twice as much as milk powder, diapers and clothes. Maybe it will be better after I am six years old. At least I can take care of myself without watching all the time.
2. There are not enough people. One child can make the whole family run around, and two can be imagined. What's more, the elderly have too many grandchildren and need to pay for a nanny. We start from the new moon until the children go to kindergarten.
3. the battle between dragon and phoenix. I think as long as there are boys, the home will not be clean, let alone auspicious. The reality is that one loves to make trouble and the other loves to cry. At home, chickens fly and dogs jump, and parents are helpless. It's quiet every day. The two guys just grab things and never stop.
In a word, twins are a blessing from their previous lives, so we should cherish and cherish them.
Twins are rewarded handsomely. You see, as long as others have only one child to survive, you have two children at once. This is a double surprise, isn't it? What's more, the twin sons and daughters are here, and I don't know how happy I am!
But twins, especially twins, are hard to find. Two children were born together and grew up together. They are playmates, they can learn from each other and compete with each other, which is a great thing. But twins are also different from only children:
Many people find it easier to have two children at a time. As we all know, the risk of twin pregnancy and childbirth is more than twice as high as that of singleton, but many people have not experienced it and are not clear. It happens that there are several pairs of twins among our relatives, and we know something about them.
It is said that "when a sheep is released, it is a flock of sheep", but taking care of children is not as simple as herding sheep. Eat, drink, sleep and be careful. The twins' breast milk is basically not enough, and mixed feeding makes their mother very tired. The saddest thing is that when the little guy is sick, he stays together, and the adults are busy.
Therefore, if you have twins, it must be very happy and a special gift from God. After three years old, twins are very cute. If twins are obtained by other means, it is technically difficult, which is not good for adults and children. It's best to let nature take its course.
The second child, twins, was conceived naturally. Neither of them has a twin gene, and they have not taken any medicine. It was the first time that two people (twins) said they didn't believe it. It's a week before the full moon. Although they all brought their own babies, they were all satisfied. There is nothing good about it. They are happy to have twins. What's more, the twins are pregnant, and they have been afraid of their two sons before. Because Dabao is a boy, even the twins are sons. So lucky to have twins, anyway, twins are happier now, satisfying Bao's little lover and grandparents' grandchildren. Now one person uses 12/ 14 tablets a day, and two people use about 25 tablets a day [laughs] [laughs]
It is auspicious to have children and dragons, and it is also what every family longs for.
For children, two children are the same age, there will be no generation gap and estrangement, and boys tend to be extroverted and rational; Girls are often inner show and emotional. The two children grew up together and exchanged what they needed. It is a rare resource for children.
For parents, two children are raised together, and at the same time, they experience the differences and fun of being parents of boys and girls, and children can also add more laughter to the family. After growing up together, parents no longer consider having a second child and have more time to themselves.
For the family, the children's resources are enjoyed, and the family expenses are greatly reduced. At the same time, it also brought more laughter to the family.
Of course, everything has advantages and disadvantages, and the advantages of twins definitely outweigh the disadvantages.
Sure! You can't have twins if you want to. If there is no twin gene in the family, the chances of twins are very, very small. The twins represent a blessing. In the countryside, if anyone gives birth to twins, people in the surrounding villages will congratulate them and say how lucky they are.
The twins are the result of simultaneous fertilization of multiple eggs. People with this constitution ovulate more every month, while normal people only have one row, which is about 1 mm square to the naked eye. White. Drugs can interfere with ovulation, and some can cause ovulation with drugs. If the fertilized egg is fertilized and formed, it will divide again. Then they grow up separately, which means identical twins. They are essentially the same person and look exactly alike. If two eggs are fertilized at the same time, they will grow separately. That is, multiple eggs, twins or multiple births. They are completely different individuals, and they are not very similar when they grow up. It may be the same sex or the opposite sex. So the probability of twins is very low.
Everything has two sides. On the bright side, 10 can have a baby once a month. If you plan to have a second child, you don't have to go through two pregnancy reactions. Twins usually have to plan their stomachs in 36 weeks, so it's no problem to have a baby once! The disadvantage is that the baby born at 36 weeks is not necessarily better than the baby born at 40 weeks. The most difficult thing is that the mother's breast milk may not be enough after the baby comes out. It is difficult for a mother to take care of two babies at the same time. I have a few examples around me. The mother sleeps with one baby, and the other sleeps with grandma or nanny or sends the baby back to his hometown. This will inevitably lead to insufficient intimacy with oneself, and children will gradually show different intimacy with their parents when they grow up.
It's a good thing to see twins at present. It is easier to solve two children at once, so that adults can suffer less, and the old man and the two children watch together. However, twins are hard to find, and it is a blessing to have twins, so you can have fun: of course, there is no need to be upset, because the probability of having twins is very low. Fortunately, the birth dates of the two children are staggered. Let it be.
Many couples want to have twins after marriage, but the probability of having twins is not very high. Giving birth to twins is a blessing in life. Lovely twins, every move, every smile, are so cute. With twins, the plan of having a second child was completed immediately. Taking one child and two children together can save the time gap. The two children have companions since childhood, and they are not lonely. They will grow up in the future.
