Twins in Palo Alto survive rare pregnancy


Kate and Annie Carlson are just 34-days-old, but already have been through a tremendous ordeal. They were rare, high-risk monoamniotic twins, meaning they shared the same amniotic sac. The condition occurs in less than one-percent of all twin pregnancies in the nation. Doctors at Packard Children's Hospital were able to safety deliver the twins, 10 weeks early.

"At 30 weeks their heart rates dropped because they got tangled in each other's umbilical cords, so I was rushed in the emergency room and they delivered them so it was pretty scary," said Allison Carlson, the mother.

First-time parents Kevin and Allison Carlson hope to take the babies home by Christmas or New Year's. After surviving quite an ordeal, the couple's big concern right now is trying to tell their daughters apart.
