The average length at birth for a full-term baby is 19 to 20 inches (about 50 cm). But the range for most newborns is between 18 and 22 inches (45.7 to 60 cm). If your baby tops the length charts, you might expect him to tower above his classmates one day. But a long infant won't necessarily become a tall adult just like short babies don't always turn into small-statured people. In fact, fetus size is determined by the mother's diet and the health of the placenta.
While touring in the summer of 1878, Anna was pregnant for the second time. The boy was born on January 18, 1879, and survived only 11 hours. He was the largest newborn ever recorded, at 23 pounds 9 ounces (10.7 kg). For this he was posthumously awarded a Guinness World Record. And do you know how tall the baby was at birth?
