Sara and Bill Thistlethwaite had been expecting twins, what they did not know was that they were going to be gifted with mono mono twins. Monoamniotic twins lay in their mother’s uterus sharing the same placenta (with separate umbilical chords) and amniotic sac. These twins are always monochorionic and identical. It was a great surprise for everyone because the chances of having such babies is of 10,000 to 1 ratio. Because the twins are attached to the mother with a single placenta and amniotic sac the delivery is considered to be very risky. The couple was still very eager to go through all the difficulties for their rare twins.
