If all goes as hoped, she'll have four more weeks to come up with four more names for the six babies yet to be born.
Karoline Byler, 30, checked into Bayfront Medical Center on Monday night after a weekly prenatal visit to her obstetrician, said her husband, Ben.
Dr. Karen Raimer wanted Karoline monitored for the rest of her pregnancy after she reported some contractions. An exam showed the cervix had shortened. A cervix needs to remain longer and closed until delivery to support the babies. Earlier in the pregnancy, doctors had put in a device to help keep it closed but it had opened some, Ben said.
The optimum gestation for higher order multiples is at least 30 weeks; a normal gestation for a single baby is closer to 40 weeks.
If all of the babies survive, the Bylers will be parents to Florida's first sextuplets.
Karoline Byler has polycystic ovarian syndrome, which makes it difficult to conceive. When the Bylers decided to give their daughter, Zoe, a sibling, the condition had worsened. Karoline turned to fertility treatments.
The result: five boys and a girl.
