For twins Amy and Katie were Â­incredibly born 87 days apart. Maria went into labour four months early, giving birth to Amy â but Katie did not arrive until three months later. Their incredible births will now Â­become a Guinness World Record for the âlongest interval between the birth of twinsâ. The previous record is 84 days.
Both types of twin are carried in the same uterus at the same time, so their birth environment is the same. Research shows that the frequency of monozygotic twinning is one in 240 births. Fraternal twins are twice as common. In vitro fertilization (IVF) techniques are more likely to create dizygotic twins.
