Monoamniotic twins (“mono mono” twins) are identical twin babies who share the same amniotic sac inside of the uterus. The chance of having a pair of mono mono twins is quite low, at a rate of around 1 in every 10,000 pregnancies.

Here is where the story gets even more unbelievable: On May 15, just five days after the first rare birth, mono mono twins JaNiya and Amaya McCail were born via scheduled cesarean section at Ohio Akron General Medical Center. The hospital even acknowledged the rarity of this occurrence calling it “statistically impossible.”
