Among the group of physicians, nurses and administrative workers, 18 of the women are now mothers.
Kristy McDowell, a labor and delivery nurse, was the first to have her baby on May 13. At 32 weeks, McDowell welcomed a girl, Priscilla, who weighed 4 pound, 8 ounces.
"She's [now] the biggest out of all of them," McDowell said of her daughter. "She's very happy, always smiling -- doesn't cry unless she's hungry."
McDowell said each day she'd come into work and more and more of her colleagues would reveal their pregnancies.
"We had a list at the nurse's station and somebody was always adding their name to it," she said.
Sarah Dixon, a secretary in the labor and delivery unit, welcomed a girl, Jensyn, on Sept. 11 weighing 5 pounds, 10 ounces.
"She's a double rainbow baby and [myself] and her older three siblings, we hold her all the time," Dixon said. "She's very special."
Assistant nurse manager Jocelyn Laake said the hospital is one big family.
"Then to get to share this moment in the lives of so many people you work with...is truly a blessing."
The women said they are excited to see their children grow up together.
