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.

What week are twins usually born?

A little more than half of twin pregnancies end in preterm delivery (before 37 weeks). While 40 weeks is the full gestation period of the average pregnancy, most twin pregnancies are delivered at approximately 36 weeks (range 32-38 weeks depending on the type of twin pregnancy).

Why do twins have lower birth weight?

In singletons, the risk of adult disease is inversely related to birthweight across the birthweight spectrum (2,3). Twins, as a population, are born lighter than singletons, with the normal distribution of birthweights for these infants shifted to the left of the normal singleton distribution (4,5) (Fig.
