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.

Fraternal twins â the most common kind â occur when two separate eggs are fertilized by two different sperm. Each twin has his or her own placenta and amniotic sac. The twins can be two girls, two boys, or a boy and a girl. Genetically, they're no more alike than any other siblings. Identical twins occur when a single fertilized egg splits and develops into two fetuses. Identical twins might share a placenta, but each baby usually has a separate amniotic sac. Genetically, the two babies are identical. They'll be the same sex and share physical traits and characteristics.
