The advantages of multiple births, including twins, and especially the advantages of twins, are well known, so I won't repeat them here.
The "bad" things about twins are not as well known to most people, so they are highlighted here.
There are two aspects:
The "bad" of multiple births***;
The "bad" that is unique to LW.
First, the benefits of multiple births, including twins, come at the cost of additional risks to mother and baby over and above those of a single birth.
The risks to the mother from a multiple pregnancy include:
Increased risk of gestational hypertension, and pre-eclampsia;
Increased risk of gestational diabetes; and increased risk of developing diabetes during the lifetime after delivery. Gestational diabetes also increases the risk of respiratory disorders and hypoglycemia in newborns;
increases the chance of obstructed labor and cesarean sections;
and increases the risk of postpartum depression.
Risks to the fetus associated with multiple pregnancies include:
Impact on fetal growth. Multiple fetuses are usually more likely to have growth problems than a single fetus. These include low birth weight, especially developmental inconsistencies, where one fetus weighs significantly less than the others;
Impact on the accuracy of screening test results for inherited disorders . It is known that many inherited developmental defects can be detected in advance by prenatal screening, thus avoiding the need to avoid the birth of infants with severe developmental defects. In multiple pregnancies, the accuracy of test results can be compromised by interference in sample acquisition;
Twin-fetal transfusion syndrome . In monochorionic-diamniotic twins, twin-to-twin transfusion syndrome may occur, in which there is an imbalance in the blood supply between the two fetuses, with one fetus "stealing" blood from the other, resulting in developmental imbalance and injury;
Preterm labor. Preterm labor is the most common complication of multiple pregnancies, more than half of all twins are born prematurely, and three or more pregnancies are often unavoidable. We know that preterm labor, especially in babies born before 37 weeks of pregnancy, can increase the risk of short- and long-term health problems, including breathing, feeding and warmth problems. As well as longer-term risks such as learning and behavioral disorders, and the development of some diseases in adulthood. Very early preterm babies (babies born before the 32nd week of pregnancy) are at greatly increased risk for death or serious health problems, even with the best medical care.
Increased risk of cerebral palsy . Cerebral palsy is a serious complication that occurs perinatally as a result of fetal brain damage, and the chances of it occurring are increased in multiple pregnancies, especially premature births.
In addition to the "bad" side of multiple births, there is a particular "bad" side of LWBs, in that the "phoenix" faces additional fetal development and a lifetime of birth defects and vulnerabilities.
A number of disadvantages have long been observed for girls in the twins and phoenixes model.
The explanation for this phenomenon is that the female fetus is thought to be exposed to male hormones during the development of the twins in utero***, resulting in a number of unfavorable effects that not only affect development in utero, but also developmental defects that can affect after birth, and even throughout their lives, a theory known as the "Twin testosterone transfer hypothesis This theory is called the "twin testosterone transfer hypothesis".
The reason it's called a hypothesis is to say that more evidence is needed to confirm it.
A recent study from Sweden, the largest to date in this area, explores this further.
In this study, researchers recorded and analyzed data on 13,800 pairs of twins born in Norway between 1967 and 1978.
The results found that women in LW twins showed several disadvantages over a follow-up period of more than 30 years, compared with other types of twin groups.
For example, they were 15 percent less likely to complete high school and nearly 4 percent less likely to complete college.
They were 6 percent less likely to have a lifetime birth rate and almost 12 percent less likely to marry.
Economic income is also significantly lower than the average for women in society, and 8.6 percent lower than for women in female twins.
Even these differences remain even when the boy in the LW twins dies shortly after birth. This means that the differences are not due to postnatal differences in upbringing caused by parental "son preference", but are more likely to be due to congenital differences, i.e., exposure to androgens in utero.
In summary, it is clear that although multiple births, including those of twins and phoenixes, often bring joy and good fortune to people, these "good things" come at a price.
Of course, these "costs" are not enough to guide and influence people's reproductive choices, especially when twins or multiple births occur naturally, because naturally occurring multiple births are rare.
However, with the widespread use of assisted reproductive technologies, including ovulation enhancers and in vitro fertilization (IVF), it is true that people have been able to actively choose to have multiple pregnancies.
In fact, in the last 30 years, there has been a substantial increase in the number of multiple pregnancies worldwide in general by a factor of several.
When you want to choose to have a multiple pregnancy through assisted reproduction, you need to think carefully, not just about the "good" side, but also about the "bad" side.
My family is the dragon and phoenix child, a sister, a brother.
In a nutshell, the birth of a baby is a blessing that can never come by.
There are a lot of good aspects:
1. Some of them depend on genetic inheritance and whether the family has a tradition of giving birth to twins; some of them need to rely on technology, such as ovulation promotion or monitoring or something. It is very good for the mom or for the family to get two at once, and the mom doesn't have to suffer a second time.
2. Two little ones. For children, having the closest playmates from a young age is very beneficial to their development and growth. This comes in handy for families with a single child, who sometimes have to think about going outside every day to find other kids to play with, and twins come in handy.
3. Three Sheep. The main point is that the mother's love for the child, the father's love for the child, there is the sister's love for the brother or the brother's love for the sister, I have always felt that the two big and two small, two men and two women, the two "good" word of the family is the most complete, is the family's greatest asset.
The bad aspects, in fact, relative to the good aspects are nothing, it is a small matter.
1. Financial deficit. The two spend more than one, from the womb onwards, whether it is milk powder, diapers, clothes, and so on, are twice as much. After the age of six may be better, at least life can take care of themselves, do not have to watch all the time.
2, not enough manpower. One child can make the whole family go round and round, two can be imagined. What's more, the old man's grandchildren are too many, the schedule can not be arranged, you need to spend money on nannies, we started from the sister-in-law, until the child went to kindergarten.
3. Dragon and Phoenix struggle. I think as long as there are boys, the house will not be clean, let alone dragon and phoenix. The reality is that one loves to make a fuss, one loves to cry, the family chicken jumps, parents are very helpless. There is not a single day that is clean, the two guys are just grabbing things, no end.
All in all, the twins are a blessing in a previous life, and they should be cherished and loved.
The twins would have been a great prize, you think ah, other people seek only a son, you have two at once, double surprise is not it? The first thing you need to do is to get your hands on a new pair of shoes or boots, and then you'll be able to get your hands on a new pair of shoes or boots!
But twins, especially twins, are a rare occurrence. The two children were born together, grew up together, from a young age, both playmates, but also can learn from each other, each other competition, it is really the best thing. But twins are also different from individual children:
Many people think that having two at a time saves them a lot of trouble. Unbeknownst to them, the risks of pregnancy and childbirth are more than double for twins, but many people just don't know that because they haven't experienced them. It just so happens that we have several twins in our family and have learned a bit about them.
It is said that "a sheep is a sheep, a flock of sheep is also a sheep", but bringing up children is not as simple as sheep herding. The first thing you need to do is to make sure that you have a good understanding of what you are doing and how you are doing it. The twins' breast milk is basically not enough, mixed feeding to the mother also tired enough. The saddest thing is that if the little one is sick together, adults are even more busy.
So, if you have twins, it must be a very happy thing, a special gift from God to you. The twins are adorable when you get past the age of three. If you get twins through other means, it is technically difficult and not good for the health of the adults and children, so it is better to let nature take its course.
The second child of the dragon and phoenix, natural conception, both sides do not have the twin gene, and did not take medication, the first ultrasound said two (twins) a little bit do not believe that there is still a week on the full moon, although they are all their own to bring, but is very content, there is no good, not good, pregnant with twins are very happy, not to mention the dragon and phoenix, pregnant with the child, we have to give birth to the two boys, because the eldest is a boy, so even if the twins are a boy, he is not a boy, he is a boy, he is a boy. The first is that the first two children are not the same, so even if the twins and is a son, I also recognized, the pressure again big no way, so lucky to have twins, no matter what is to be, now the dragon and phoenix child is more happy to satisfy the baby father to be a little lover, but also to satisfy the grandparents want to grandchildren, and now a day a person with 12/14 pieces of diapers, the two people a day almost with 25 pieces of diapers or so [embarrassed laugh] [embarrassed laugh] [embarrassed laugh] [embarrassed laugh] [embarrassed laugh]
The dragon and the phoenix, the children, that is the heavenly blessing, is what every family seeks for.
For the children, the two children are the same age, there will not be any generation gap and disconnect, the boy tends to be outward-looking, rational; the girl tends to be inward-looking, emotional. The two children grew up together and shared their experiences with each other. It's a rare resource for children.
For parents, two children raised together, while experiencing the different and fun as parents of male and female babies, children can add more laughter to the family. Growing up together, parents no longer consider the second child, have more of their own time at their disposal.
For the family, the child resources **** enjoy, on the family expenditure side is also quite a big reduction. At the same time, it also brings more laughter to the family.
Of course, there are disadvantages to everything, and the benefits of having a baby outweigh the disadvantages.
Of course it's good!
The chances of having a baby are very, very small if there is no gene in the family for having a baby. A baby represents good fortune, and in the countryside, if someone has a baby, the people in the surrounding villages will go to congratulate them and say that they are lucky to have a baby.
A baby is the result of the simultaneous fertilization of multiple eggs. People with this type of constitution will have more than one at the time of ovulation every month, while normal people have only one, which is visible to the naked eye and is about 1 millimeter square. It is white in color. Ovulation can be interfered with by medication, and in some cases, medication can be used to cause multiple ovulations. If a fertilized egg is formed and splits. If a fertilized egg is formed, splits, and then grows separately, it is called a monozygotic twin, and they are essentially one person who looks exactly the same. If two eggs are fertilized at the same time and grow separately, they are polygynous or multiparous. They're polygynous, or multiple births. They're completely different individuals, and they don't grow up to look very much alike. They may be the same sex or opposite sex. Therefore, the probability of having a twins is very low.
Everything has two sides ah, the good side is a October pregnancy on the OK, if you intend to give birth to a second child do not have to go through two pregnancy reactions, the dragon and the phoenix child is generally 36 weeks to plan the abdomen, once a child with a daughter of course, it is good! The bad side is that 36 weeks out of the baby is bound to be not as good as the baby born at 40 weeks, and the most difficult thing is that after the baby comes out of the mother's breast milk may not be enough to eat, it is difficult for the mother alone to take care of two babies at the same time, there are a few examples of this around me, the mother sleeps with one of the babies, and the other one has grown up with either grandma sleeps with a nanny sleeps with the nanny or sends one of the babies back to his hometown, which will inevitably be with his own! The first thing you need to do is to get your hands on some of the most popular products and services in the world, and you'll be able to do that.
At present, how to look at the dragon and phoenix child is a good thing, a one-time solution for two children, adults less suffering, the old man two children a piece to see, but also save things. However, the dragon and phoenix fetus can not be sought, there is a dragon and phoenix fetus is fortunate, you can steal the joy: of course, there is no need to be chagrined, because the probability of dragon and phoenix fetus is very low. It is also good to stagger the birth of the two children over a period of time. The first thing you need to do is to get your hands on a new one, and you'll be able to do that.
The dragon and phoenix child is a lot of couples want to have after marriage, but the probability of dragon and phoenix child is not very high, can have a dragon and phoenix child is a lucky thing in life, lovely dragon and phoenix child every move, a smile is so love, have a dragon and phoenix child, all of a sudden to complete the plan to have a second child, and take a child and take a child and take a child together to eliminate the gap of time, the two children grew up with a companion, not lonely and lonely, and the two children have a companion, not lonely and lonely. In the future, when they grow up, they will work together and get married together, and the parents of a child can not enjoy the fun of the parents of twins, and how happy it is to have children with a daughter!
