Gestation. Giraffes are pregnant for a period between 14 and 15 months, or 453 to 464 days, one of longest gestation periods in the animal kingdom. Giraffes usually give birth to one offspring at a time, although twins are born occasionally. Because the gestation period is so long, the giraffe won't give birth to another baby for 16 months or more.
Gestation in a Giraffe Mother lasts for around 400 to 460 days. This works out to nearly 13 to 15 months of pregnancy. Baby Giraffe's are born after nearly 400+ days of pregan â¦ ancy. At birth, they are around 6 feet tall. That is 1.8 meters height at birth. They weigh around 100 to 150 pounds at birth.
