A RARE MIRACLE: AUBURN MOTHER CELEBRATES THE ARRIVAL OF MONO MONO TWINS

When Auburn native Taylor Medley attended her initial pregnancy scan, she anticipated routine news. Instead, the ultrasound revealed two babies and introduced her to an exceptionally rare medical journey. Further research confirmed she was carrying monochorionic monoamniotic twins—commonly known as Mono Mono twins—where both siblings share a single placenta and amniotic sac, a occurrence seen in less than one percent of twin pregnancies.

Dr. Mark Underwood, Chief of Neonatology at UC Davis Medical Center, explained that Mono Mono twins develop when a fertilized egg divides late, between the eighth and twelfth day after fertilization. This unique condition carries significant risks, including umbilical cord entanglement, growth issues, premature birth, and Twin-to-Twin Transfusion Syndrome. Because of these potential complications, Medley was admitted to UC Davis for roughly a month of rigorous, round-the-clock medical monitoring.

Despite the stress and demanding daily evaluations, the careful management ensured the safety of both infants. On November 10, at 32 weeks, Medley delivered her daughters, Araya Lynn and Reign Leann, via cesarean section. Remarkably, both girls were born at the exact same minute—12:38 p.m.—and overcame the risk of cord entanglement without major complications. Following a period of specialized neonatal care, both babies demonstrated strong health, allowing the family to plan for their joyful transition home together.
