BORN BIG High-birthweight newborns, such as this 4-day-old 19-pound baby (center) born to a diabetic mother, face health risks into adulthood.
The heaviest baby ever was born in the US in 1879: 23 pounds, 12 ounces (10.7 kg), but he died 11 hours after being born, as too much or too little above/below the average value decreases fitness. The heaviest baby also to survive was born in 1955 in Italy: 22 pounds, 8 ounces (10.15 kg) at birth.
