| | Multiple birth |
 | | The most common form of multiple birth is twins (two babies), but cases of triplets (three), quadruplets (four), quintuplets (five), sextuplets (six), septuplets (seven), octuplets (eight), and nonuplets (nine) have all been recorded with all siblings being born alive. |
 | | The Humair septuplets (born on January 14, 1998 in Abha, Saudi Arabia) were the world's second surviving set of septuplets, born to a 40-year-old mother. |
 | | The smallest of the octuplets, Odera, died a week after birth. |
