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.
1 The average birth weight of full-term twins (37 weeks or later, compared to 39-40 weeks for singletons) is around 5 Â½ pounds each, though one baby often weighs more than the other. For most women pregnant with twins, gaining 24 pounds by week 24 is advised; a total weight gain of 35-45 pounds is generally desirable. 2  The twin who is developing closest to the exit (your cervix) is called Baby A. In 75 percent of cases, Baby A is head down before delivery; Baby B may be either head down or breech.
