gave birth to her son George six weeks ago—and he came out weighing a whopping 15 pounds 7 ounces.

“He’s a little miracle—well, a big miracle, really,” Jade King, who birthed George vaginally, told the BBC.
No one realized just how big George was until his head had emerged, at which point his shoulders got temporarily stuck and he went without oxygen for five minutes.
“There was about 20-odd doctors in the room, and that’s when it got really scary,” King recalled.

Once the baby was out, he was given a 10 percent chance of survival and transferred from Cheltenham to another hospital, in Bristol. He was kept there for four and a half weeks and then went home, and just received normal results from an MRI.
“It might just be that he’s a little big slow with his learning,” his mom added. “So hopefully it’s just minor little things.”
George has only gained a pound since his birth, and has been wearing clothes sized for a 3-to-6-month old from day one (his mom had to give away all the newborn onesies that were awaiting him at home). He is the second-biggest baby ever born vaginally in the UK, according to various reports; the larger baby weighed just an ounce more.
In George’s case, doctors were unsure of what caused his hugeness, the medical term for which is called macrosomia. But the condition is often caused by mom having had gestational diabetes during her pregnancy, according to the American Congress of Obstetricians and Gynecologists.
Both King and her doctors were shocked at George's size—which is "bizarre" to Schwarzschild. "You estimate the fetal weight, always," she noted. "I mean, you didn't ever feel her or talk to her or measure her? That doesn't make any sense."
Meanwhile, the large babies themselves face a higher risk of high blood pressure, diabetes, and stroke later in life.
Though babies this huge are rare, they are certainly not unheard of—and, according to at least one recent study, in Oregon, they are becoming even more commonplace. Oregon has seen at least two 14-pound-plus babies born every year since 2005. In 2012, in China, a 15.5-pound baby boy was born, via C-section, setting a countrywide record. A 19-pound baby was born via C-section in Indonesia in 2011. And, that same year in Texas, a 16-pound baby boy was born—sans C-section—and promptly nicknamed “Moose.”
According to the Guinness World Records, Ann Bates gave birth to the biggest newborn ever, in 1879 in Ohio, when her baby weighed in at a whopping 23 pounds, 12 ounces. He died within a day. But a 22-pound, 8-ounce baby born in Italy, in 1955, survived.
