Do twins know they are in the womb together?

Yes, studies show twins are aware of each other in the womb, starting around 14 weeks, and actively interact by touching and reaching for their co-twin more than themselves or the womb wall, indicating an early social bond and developing self-other differentiation. This pre-birth contact, which can involve stroking or planning movements towards the other, suggests twins begin recognizing and interacting with their sibling as a separate entity early in development, not just an accidental touch.

Do twins hug in the womb?

They wouldn't have cuddled in the womb because they would have been in different sacs. Ali Lorraine Cooper unless they were Monoamniotic, which are twins that share a sac.

Can you tell if twins are conjoined in the womb?

There are no specific symptoms that indicate a conjoined twin pregnancy. As with other twin pregnancies, the uterus may grow faster than it does with a single baby. And there may be more tiredness, nausea and vomiting early in the pregnancy. Conjoined twins can be diagnosed early in the pregnancy using an ultrasound.

What happens to a twin that dies in the womb?

When a twin dies in the womb, it's often reabsorbed by the mother's body or the surviving twin, known as Vanishing Twin Syndrome, usually harmlessly in early pregnancy; however, if death occurs later, especially in identical twins sharing a placenta, the surviving twin faces increased risks like cerebral palsy, preeclampsia, or premature birth, requiring careful monitoring for complications, notes The Lancet, UCSF Benioff Children's Hospitals, Twins Trust, Cleveland Clinic and American Pregnancy Association, says BabyCentre UK, O&G Magazine and NIH.

When do twins start to bond in utero?

Bonding starts in the belly.

Researchers from the University of Padova in Italy studied 3D ultrasounds of five sets of twins in the womb. They found at just 14 weeks the pair seemed to be touching each other.

What is a daisy baby?

A "Daisy Baby" is a term for babies affected by Twin to Twin Transfusion Syndrome (TTTS), a serious condition in identical twins sharing a placenta, or related complications like TAPS, SIUGR, and TRAP. The name comes from the Twin to Twin Transfusion Syndrome Foundation (TTTSF), symbolizing twins thriving like daisies after surviving the "storm" of the condition, with their logo often showing two daisies from one stem, representing the shared life and journey. 

How common is it to miscarry twins?

Twin pregnancy has a higher miscarriage risk than singletons, with overall loss rates varying, but often cited around 5-13% for both, though the biggest factor is chorionicity: Monochorionic (MC) (identical, sharing placenta/sac) twins face much higher early loss (around 10-60%) due to complications like TTTS, while Dichorionic (DC) (fraternal or identical with own sac) twins have lower rates (around 3-10%), similar to or slightly above singletons, with risk decreasing significantly after 24 weeks. A common event is "vanishing twin syndrome," where one twin is lost early. 

Can you abort one twin and keep the other?

Yes, it's medically possible to selectively terminate one twin while continuing the pregnancy with the other, a procedure called selective reduction or multifetal pregnancy reduction, often done due to health risks for the mother or severe abnormalities in one fetus, typically using ultrasound guidance and injections to stop the target twin's heart. This procedure reduces the risks associated with twin pregnancies (like preterm birth) but carries risks, including potential loss of the remaining twin, and is a complex medical and emotional decision. 

How often do twins absorb each other in the womb?

Twins absorbing each other, known as Vanishing Twin Syndrome (VTS), is quite common, occurring in up to 30-36% of twin pregnancies, where one embryo stops developing and is reabsorbed by the mother or the other twin, often in the first trimester, usually undetected unless early ultrasounds are used. While it's a frequent event, especially with IVF multiples, it often has no impact on the surviving baby, whose prognosis is usually excellent, though it can involve mild symptoms like spotting or cramping.
 

Why can't you say siamese twins?

You can still say "Siamese twins," but it's outdated and often replaced by the more accurate and sensitive term, "conjoined twins," because the original term links to historical "freak shows," isn't geographically accurate for most cases (as it comes from Chang and Eng Bunker of Siam, now Thailand), and can feel dehumanizing, similar to outdated terms for other conditions. "Conjoined twins" is the preferred medical and respectful term for twins physically joined in utero. 

What is the earliest twin can be detected?

You can often see twins on an ultrasound as early as 6 to 7 weeks into a pregnancy, especially with a transvaginal scan, though it's common for them to be confirmed at the standard first-trimester ultrasound around 8-14 weeks, with the 12-week scan being very reliable for detection and placenta type. Sometimes, higher hCG levels or earlier symptoms might hint at twins, but an ultrasound is the only way to confirm.
 

Can two different genders be conjoined twins?

Yes, conjoined twins can be different genders, though it's rare, usually occurring in cases where one twin develops with different chromosomes (like XO, female) from the original XY (male) conception, or in cases where identical twins later identify with different gender identities (like Lori and George Schappell), but genetically they start the same. Typically, conjoined twins are identical and thus the same sex, but unique genetic circumstances or differing gender identities make opposite-sex pairings possible.
 

What does God say about twins?

God's perspective on twins, particularly in the Bible, highlights their unique destinies and the fulfillment of His plans through them, most famously with Jacob and Esau, where God declared the younger would rule the older, signifying divine purpose over birth order. The Scriptures show God using twins to form nations, illustrate complex family dynamics, and reveal His sovereign choice, with other biblical twins like Perez and Zerah and the ship's figurehead (Dioscuri), showing twins as significant, sometimes symbolic, figures in His unfolding story. 

Who carries the gene for twins?

The tendency for fraternal twins is genetic and carried by the mother, specifically a gene for hyperovulation (releasing multiple eggs) that she inherits from her mother or father, but it's the woman who ovulates multiple eggs who has twins, not the father. A father can pass the gene to his daughters, increasing their chances, but his own family history of fraternal twins doesn't directly affect his partner's odds, though factors like age, diet, and fertility treatments also play a role. Identical twins, however, are generally not genetic and occur randomly when one fertilized egg splits.
 

Does one twin sometimes eat the other in the womb?

Vanishing twin syndrome was first recognized in 1945. This occurs when a twin or multiple disappears in the uterus during pregnancy as a result of a miscarriage of one twin or multiple. The fetal tissue is absorbed by the other twin, multiple, placenta or the mother.

What happens if one twin dies in the womb?

If one twin dies in the womb, outcomes vary: early first-trimester loss (vanishing twin) often has no issues for the survivor, but later loss, especially in shared-placenta monochorionic twins, poses significant risks like brain injury, developmental delays, preterm birth, and organ damage due to shared blood vessels or release of substances from the demised twin, requiring close monitoring and specialized care. The surviving twin faces increased risk of complications like cerebral palsy, learning disabilities, or gut issues, but many still develop healthily.
 

Can twins have Down syndrome?

Yes, twins can have Down syndrome, though it's rare, with scenarios including both twins having it (identical or fraternal), or only one twin having it, even in identical sets due to genetic events after conception, according to sources like the TODAY Show and Down Syndrome Education. 

Can twins stay away from each other?

The unique bond twins share can create a "built-in best friend". But once distance is put between the pair, loneliness can take over. For many twins, living away from each other is out of the question.

Are twins considered high risk pregnancy?

Yes, twin pregnancies are considered high-risk because they significantly increase the likelihood of complications for both the mother and babies, such as preterm birth, preeclampsia, gestational diabetes, fetal growth restriction, and anemia, requiring more intensive prenatal monitoring. The uterus is designed for one baby, so carrying multiples puts extra strain, leading to these elevated risks, though many twin pregnancies still result in healthy outcomes with proper care.
 

What causes stillbirth in twins?

Stillbirth in twins, especially monochorionic (sharing a placenta), is often caused by twin-specific issues like Twin-Twin Transfusion Syndrome (TTTS), uneven placental sharing leading to growth restriction, or umbilical cord problems (entanglement, knots, compression). Other factors include infection, placental issues (abruption), congenital abnormalities, prematurity, and maternal conditions, with the type of placenta (monochorionic vs. dichorionic) significantly impacting risk. 

What week is the highest risk of miscarriage with twins?

Sadly, pregnancy loss in the first 12 weeks is common. The risk of losing a baby in the first two trimesters of a twin pregnancy is slightly higher than with a single pregnancy.

What are momo twins?

Monoamniotic twins are identical twins that share an amniotic sac, the fluid-filled sac that holds the baby during pregnancy (also known as the “bag of waters”). Normally, identical twins each have their own amniotic sac. Monoamniotic twins are a rare type of “monochorionic” twins, meaning they also share a placenta.

What is the safest type of twin pregnancy?

The safest type of twin pregnancy is Dichorionic-Diamniotic (DCDA), where each twin has its own placenta (chorion) and its own amniotic sac, meaning they don't share blood supply or resources, reducing risks like Twin-Twin Transfusion Syndrome (TTTS) and cord entanglement. DCDA twins can be fraternal (non-identical) or, rarely, identical if the embryo splits very early. This setup provides the best individual support systems, making it the lowest-risk scenario compared to pregnancies where twins share a placenta (monochorionic).
 

What is the main cause of twins?

People have twins through two main ways: identical (monozygotic) twins from one egg splitting, which is random, and fraternal (dizygotic) twins from two eggs fertilized by two sperm, often influenced by genetics, maternal age (over 30s), and fertility treatments. Factors like family history, previous pregnancies, and certain genes (FSHB, SMAD3) increase chances for fraternal twins, while identical twins result from an unpredictable early embryo split.
