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 bit 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.
