A tiny, premature baby survived after doctors kept her warm by putting her in a sandwich bag from the hospital cafeteria.

Lexi Lacey was given a 10 percent chance of survival after being born 14 weeks early, weighing just 14 ounces.

She was so tiny that doctors had to use the smallest insulating jacket they could find - a six-inch wide plastic sandwich bag from the kitchens at Worcestershire Royal Hospital.

Amazingly, Lexi survived and is now a bouncing 11-week-old baby weighing a healthy 5 pounds, 6 ounces.

"The doctors told us they had never known a baby born as prematurely as Lexi survive,” said Lexi’s mother, Chelsea Rowberry, 17.

"She was so tiny the only thing they had to keep her body temperature warm was a sandwich bag from the hospital canteen - it's incredible to think that saved her life.”
