11 Things You Didn't Know About Twin Pregnancies

Experts share their advice for women who are pregnant with twins.

No. 10: Labor (and delivery) may come early with twin pregnancies.

Most moms carrying twins go into labor at 36 to 37 weeks, as opposed to 40 in a single pregnancy, Al-Khan says, and some may go even earlier. "Generally, if the twins are born after 34 weeks, there should not be a major concern, but a premature baby is still a premature baby," he says. "Twins are at higher risk of preterm labor and delivery and have higher degree of respiratory issues." As a result of being born too early, twins may be born at low birth weights, and such babies tend to have more health problems than babies born weighing more than 5.5 pounds.

Unfortunately, there is no evidence that bed rest alone prevents preterm labor or delivery in twin pregnancies, and the use of agents to stop preterm labor have not been proven to be effective either, he says. "Stopping premature labor is challenging in multiple gestations."

No. 11: Cesarean section deliveries may be more common in twin pregnancies.

"The likelihood of having a C-section is absolutely higher in twin pregnancies," he says. "There is also a higher incidence of the baby being in breech position among twins than singletons." When the baby is in a breech position, a C-section delivery is usually required.
