Carrie Zirbes and her husband, already parents of three, were stunned to learn they were expecting “mono mono” twins, an extraordinarily rare condition occurring in roughly 1 in 10,000 pregnancies.
Fiona and Phoebe shared one placenta and one amniotic sac, creating serious risks from tangled umbilical cords and an uneven blood exchange between the babies.
Fiona initially needed help breathing, and both sisters spent time in the neonatal intensive care unit.
But After 30 weeks of uncertainty and dedicated care, the girls became healthy enough to go home with their family.
Now, Fiona and Phoebe have celebrated their first birthday and are happy, healthy, and thriving.
