Conclusions These data support the proposition that twins perform less well academically than singletons. Low birth weight has a negative association with subsequent academic achievement in early adulthood, with the effect being stronger for twins than for singletons.

Do twins develop faster than singletons?
Conclusion: Twin infants do not have accelerated maturation and improved neonatal outcome compared with matched singleton infants born at the same gestational age because of preterm labor.
Are twins smarter than singletons?
Twins on the average seem to have lower IQs than singletons. The best estimate for this group difference is 4.2 IQ points (less than one-third of a standard deviation), with a great divide between study outcomes of less vs more recent birth cohorts (5.1 vs 0.5 IQ points, respectively).
How are twins different from singletons?
Singletons interact with you, family members, and friends. Twins, in addition to you, family members, and friends, have a constant companion with whom they have been interacting even before birth. Twins offer a unique opportunity for parents to observe how their children interact with each other.
Are twins as healthy as singletons?
Background: Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy.
Do mothers of twins live longer?
The duo found that women who gave birth to twins “outperformed” their peers who only ever had one child at a time. On average, they lived longer after menopause. They gave birth more frequently, and over the course of their lives, they raised two more children.
What is the average size of twins at birth?
Twin delivery, on average, occurs around 35 to 36 weeks. Triplets and quadruplets may come even sooner. Moms of singletons, on average, deliver at 39 weeks. Since many twin births happen early, the average twin arrives weighing about 5 1/2 pounds.
Why do twins have lower IQ?
At age 7, the mean IQ score of twins was 5.3 points lower than that of singletons in the same family, and at age 9, the score was 6.0 points lower. The lower intelligence of twins in childhood may partly be a consequence of the reduced fetal growth and shorter gestations of twins, say the authors.
Are twins less successful?
The researchers used data on 13,800 twin births between 1967 and 1978 to show that females exposed in utero to a male twin are less likely to graduate from high school (-15.2 percent), to complete college (-3.9 percent) or to get married (-11.7 percent).
Do twins have similar IQ?
Researchers found that the twins had “substantial differences” in their IQ. Tests revealed that the adopted twin had an IQ 16 points lower than her long-lost sister. This contradicts existing research that says identical twins usually have no more than 7 points difference in their IQ.
Is belly bigger with twins?
Your belly may grow bigger, and you may gain more weight, sooner. Talk to your doctor about how much you might expect to gain. When you’re carrying twins, you and your babies may be tested and checked more than you would for a single-baby pregnancy.
Are twins harder to raise?
“Having twins is not twice as hard—it’s exponentially more difficult,” says Natalie Diaz, author of What To Do When You’re Having Two and CEO of Twiniversity, a global support network for parents of twins.
How much harder is a twin pregnancy?
7: If you’re pregnant with twins, you may gain more weight than if you’re carrying one child. “With twins, mothers gain more weight as there are two babies, two placentas, and more amniotic fluid,” says Al-Khan. “You also need more calories for twin pregnancies.”
Do twins end up shorter?
The fixed-effects regression analysis of the sibships that included both twins and singletons showed that the twins were 0.9 cm (95% confidence interval: 0.6, 1.2) shorter than were their singleton brothers.
Do twin pregnancies grow slower?
Multiples do tend to be born smaller than single babies. But it’s not because their growth rate is necessarily slower — in fact, for twins, it’s about the same as any other baby’s until about weeks 30 to 32, when they do slow down a tad, since they’re competing more for nutrients.
Will smaller twin catch up?
Most twins, triplets and more grow and develop along roughly the same lines as their singleton peers – even those who start out much smaller will catch up in time. But there is nothing to say twins, triplets or more have to reach milestones at the same time as each other.
Do twins bring good luck?
TAIWO and KEHINDE
““We believe ‘Ibeji’ (twins) bring good luck. They represent fertility and bring love, they are a blessing to the family. Once you have twins, people believe that more and more of everything will come to you. Twins are also related to the monkey spirit and more specifically to the Edun monkey.
What are the advantages of having twins?
What are the benefits for the twins? Their buddy is always there. They’ve known each other since they can remember and that is very comforting. They are also a little more social than the average child since they are used to being with another kid since the beginning.
Are twins happier?
They examined reported levels of happiness in 1,300 sets of identical and fraternal twins. Identical twins reported similar levels of happiness, while fraternal twins exhibited greater variation in their reported sense of well-being.
How long do you stay in hospital after having twins?
“That goes up to 80 percent with triplets, and even higher for quads.” How long they stay in the hospital varies. For twins, the average stay is nine to 25 days. For triplets it’s 11 days to up to three months. And for quads or more, it’s longer.
What are the risks of carrying twins?
Why is multiple pregnancy a concern?
- Preterm labor and birth. Over 60 percent of twins and nearly all higher-order multiples are premature (born before 37 weeks).
- Gestational hypertension.
- Anemia.
- Birth defects.
- Miscarriage.
- Twin-to-twin transfusion syndrome.
