What To Expect From A Twin Pregnancy: ABCs Of Multiple Birth Imagine trying and wishing for just one child, only to have two! Statistics show that there has been an increase in twin pregnancy the past few years and this short guide should answer any questions you have to giving birth to multiples! How do twins begin? Identical twins and fraternal twins are the two types of twins. In the case of identical twins, the egg is fertilized and then splits into two cells. Since the DNA in each cell is the same, both children will have exactly the same appearance, with only minor differences like height or birthmarks. Fraternal twins are not identical. Instead of having one egg that splits into two, there are two eggs that are fertilized by two different sperm at the same time so they could be of two different sexes with different physical characteristics. Early signs of twin pregnancy An early sign of twin pregnancy is excessive morning sickness and extreme fatigue. All pregnant women experience morning sickness, but those who give birth to multiples typically experience more than usual. Exhaustion is another early sign of twin pregnancy. Again, it is not unusual for pregnant women to be tired more than usual, but twin mothers typically experience increased exhaustion. Twins are hereditary and so if you are feeling excessively tired, are often nauseous and twins run in your family, you very well could be giving birth to multiples! Twin pregnancy facts With twins, youll have to prepare for double the trouble! This means you will probably be gaining more weight than with a single pregnancy. Due to this extra weight, a pregnancy with twins can often be more uncomfortable severe exhaustion, stronger backaches and headaches, etc. So get plenty of sleep and rest. Try a pregnancy massage, a great stress reliever to those giving birth to multiples. Also be prepared for a possible c-section, as with multiples this is the more common way of giving birth. Because a twin pregnancy is considered a high risk pregnancy, you will probably need to consult your obstetrician more often than if you were having a regular pregnancy. Do not be fazed as this is quite common with twins. Having a twin pregnancy is most certainly a mixed blessing. Whilst having two children is an amazing experience, the pregnancy itself can be tough so make sure to take care of yourself.

 Twins are a kind of multiple births, i.e., when a woman gives birth to more than one baby at the same time. Twins occur when more than one egg is fertilized or when the same egg is fertilized more than once by one or two sperm, leading to formation of more than one fetus. Conjoined twins are identical twins who are joined together somewhere in the body. Conjoined twins are monozygotic twins, in the sense that they share the same zygote. Sometimes, they also share some vital internal organs. Formation of conjoined twins is believed to be the result of late twinning. Because the embryo may not fully split when the twinning occurs more than twelve days after the egg is fertilized, it may result in the formation of conjoined twins. This may be due to genetic or environmental factors. Conjoined twins are also known as Siamese twins, named after the famous conjoined twins, Eng and Chang Bunker from Siam. Conjoined twin births are very rare, amounting to around one birth in every 1,00,000 births. Mary and Eliza Chulkhurst, famously referred to as the biddenden maids, are one of the earliest known set of conjoined twins. The ratio of male and female sets of conjoined twins was found to be three to one, and they are found more in certain countries like India or Africa. Conjoined twins rarely survive because of the complexity of the bodies. Most of them are stillborn or die within twenty-four hours after birth. Conjoined twins can be separated surgically if none of the vital organs are involved. There are different kinds of conjoined twins, depending on the part of the body where they are joined. These are cephalopagus, craniopagus, craniothoracopagus, dicephalus, iscopagus, omphalopagus, parapagus, pygopagus and thoracopagus. There are also some rare kinds of conjoined twins, such as parasitic twins (where one twin is not completely formed and depends on the other twin to sustain life), and fetus in fetu (where one twins fetus is present inside the body of the other twin). Some people consider separation of conjoined twins as unethical if it involves death or disability of one of the twins. Conjoined twins, if they survive, can lead healthy lives. There are instances where conjoined twins have even married and become parents. The famous Siamese twins, Chang and Eng Bunker, fathered twenty-one children in thirty-one years.

Two people who were born into the same womb at the same time are called twins. They may also have come from the same egg. Twin births are becoming more and more common due to several factors such as increasing use of fertility treatments, child births at an older age, and even genetic factors. Additionally, women with a slightly above-average build are more likely to have twins or multiple births. Certain ethnic groups are also found to have a greater twin population. One in every 250 births in the world could be an identical twin birth. Monozygotic twins are another name for identical twins. They are from a single egg that forms a single zygote that splits into two embryos. Two fetuses emerge from the two embryos in the same womb. The precise cause of this division is still unknown. Sometimes, identical twins also share the same amniotic fluid, making them monoamniotic. Otherwise, they are diamniotic. Twins sharing the same placenta are monochorionic. Those who dont are dichorionic. Only identical twins can experience this. All monoamniotic twins are also monochorionic. This depends on the stage at which the zygote divides. Twinning at the earliest stages would result in diamniotic and dichorionic twins. Twinning that occurs four to eight days after fertilization and eight to twelve days after fertilization results in monochorionic-diamniotic and monochorionic-monoamniotic, respectively. Twinning twelve days post-fertilization may result in conjoined twins. Conjoined twins are attached to each other at some place. They may be more dependent on each other physically. Since identical twins share the same sac, amniotic fluid, and placenta, there could be some complications in pregnancy. These could be a result of the entanglement of the umbilical cords or twin-to-twin transfusion syndrome because of the shared placenta. This may cause one or both the babies to be underdeveloped. Identical twins are generally of the same sex. They have identical DNA and shared genes. They may be very similar to each other, almost like mirror images. Some twins can be told apart only by their fingerprints, teeth, handwriting, or any other intricate observations. However, their personalities and character traits differ from one another. Twins are generally emotionally attached to each other and are also believed to live longer because of this attachment. Some people even believe that identical twins have their own language through which only the two of them can communicate. Some identical twins are also mirror twins they are exact mirror images of each other. About one-fourth of all identical twins are mirror twins. Sometimes, one mirror twin may have a condition where some or all the internal body organs will be on the opposite side of the body. However, these are considered to be birth defects and are extremely rare.
