Baby born naturally at 13 pounds 4 ounces is Germany's biggest

Baby Jasleen was born at University Hospital in Leipzig, Germany weighing 13 pounds and 4 ounces, and at 22.4 inches long, she is the largest newborn recorded in the country's history.

The unnamed German mother, who gave birth naturally, had an undiagnosed case of gestational diabetes, which usually occurs around the 24th week of pregnancy and can lead to larger newborns.

Doctors say mother and daughter are both well, with Jasleen remaining in the neonatal care unit.

Gestational diabetes was a factor behind the size of JaMichael Johnson, who was 16 pounds, 1 ounce, and 24 inches long when he was born in Texas in July 2011.

The Guinness Record for heaviest birth belongs to the son of Anna Bates, who suffered from gigantism. Her son was born in Seville, Ohio on January 19, 1879, at 30 inches long and weighing 23 pounds, 12 ounces, but he died 11 hours later.

The heaviest baby born to a healthy mother was a boy weighing 22 pounds, 8 ounces in Italy in 1955.
