If you're carrying more than one baby, chances are good you'll deliver early. Twins are usually born around 36 weeks -- four weeks early. Triplets arrive at about 33 weeks, and quads often make their debut at 31 weeks.
Due to the limited size of the mother's womb. multiple pregnancy is much less likely to carry to full term than singleton birth (twins usually around 34 to 37 weeks). Since some premature births often have health consequence to the babies. twin births are more often handled with special procedures than regular births.
