The longest baby ever recorded was born to Anna Bates, a woman notable for her great stature of 7 feet 11 inches (2.41 m). In January 1987, she gave birth to a baby boy who measured 28 inches (71 cm) long. Sadly, the baby only survived for 11 hours.
Anna Bates and her husband Martin van Buren Bates were the tallest married couple ever, and their son was also the heaviest baby ever recorded, weighing 22 pounds (10.0 kg).
