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.
Answer Wiki. From an old Guinness Book of World Records, the longest duration between twin births was 84 odd days. Yes, DAYS. Mrs. Peggy Lynn gave birth to Hanna on November 11 1995 and twin Eric on Feb 2 1996, 84 days later, the longest interval between twins. The previous record was held by Mrs. Danny Berg of Italy, who had Diana on December 23 1987 and her twin Monica on January 30 1988, 38 days later.
