Reasons Twins are Born Early

Why Many Multiples Arrive Before Their Due Date


Updated July 13, 2008

It's estimated that fifty percent of twins are born prior to 36 weeks gestation, almost a month before the standard 40 weeks of a singleton baby. Triplets and other higher order multiples have an even greater chance of being born early. In some cases, preterm labor can not be halted, while in other situations, risks to the mother or babies require an early conclusion to the pregnancy. Will your babies be born early? Here are some of the most common reasons why.

Mo-Mo Twins
