The Mexican news station Televisa broke the news of the 32-year-old mother's record-breaking multiple pregnancy this week, and Gawker has already stamped her with the tabloid-ready nickname "nonomom."

In a video of a news broadcast, Karla appears remarkably calm considering what lies ahead.
"Doctors tell me there are six girls and three boys," the 32-year-old said. "It's miraculous."
But science should probably take more of the credit. Up to 40 percent of in vitro fertilization pregnancies result in multiples. In extreme cases, like 'Octomom' Nadya Suleman, it's a result of multiple embryonic implants, exceeding the suggested limit of two. Suleman had 12 embryos implanted before her doctor had his license revoked.

Televisa confirmed that Karla underwent fertility treatments before her pregnancy, but didn't provide any more details. For now, her doctors are focusing on a healthy delivery.
"I just hope that everything goes well," she told the news station.
Having multiples comes with serious risks to both mom and children. Carrying so many fetuses at once can cause internal bleeding, high blood pressure, and heart problems in women, and put one or more of the babies at risk for birth defects and fatalities.
New research on risk of multiples pregnancies
Already, Karla's children are likely to arrive two months early, and will have to be placed in incubation until they reach a stable weight. Her scheduled C-section is reported to be May 20, unless she is in good enough shape to withstand their continued growth.
If all goes well, the next hurdle will be how to support and care, not only for her nine newborns, but for her four other young kids. For now, the family is living with her in-laws in Coahuila, Mexico, near the Texas border. "My husband doesn't make so much money as a tire fitter so I think we're going to need extra help with hospital costs and everything," she said in the interview.
She's hoping that sharing her story with the public will lead to some generosity. Already Ernesto Cepeda Valdes, the mayor of city where she lives, has made a grandiose promise. "We will be like godparents to those babies and give all the support we can," he told the news.
Just over the border in Houston, another mother of mega-multiples is recovering after her emergency delivery. Laura Perkins gave birth at 30 weeks to three boys and three girls ranging in size from 1 pound 10 ounces to 2 pounds 15 ounces. Five of the babies are doing well, though Perkins reports on her blog that one is in more critical state. "One baby is sick, but making progress," reads a blog update on the Perkin's site. "In the NICU, things change hourly so we're constantly getting updates."
About one set of sextuplets are born in the U.S. each year. Suleman's kids upped the ante at eight, and are considered the longest-surviving octuplets in the world. If Karla's birth is a success, it will be the first on record. Expect a flurry of reality show offers to follow. But first, give that mom a little rest.
