All common vampires remain immortal and ageless. All except for the offspring of royal first generation vampires. The only generation that can give birth to vampire babies who naturally age to mature adulthood. These unique Vampire pregnancies last 666 months or 55.5 years. The length is so long because the living dead vampire body is ill-equipped to handle bearing forth life even if it is living dead in nature. In addition, immortal children, in general, tend to age extremely slow unless they are the direct offspring of a powerful higher dimensional entity such as the Devil. Satan’s Son, The Anti-Christ, is known to be aging rather rapidly after his 2015 birth.
Birthed First Generation Vampires Are The Only Ones To Age
Once born, a vampire baby will age 10 human years for every 100 years on Earth. The vampire offspring will stop aging at the human equivalent of about 33 years old which would be 330 years old for them. So vampire children end up having some of the longest childhoods on Earth. Which is a good thing for both vampire parents and their children. There’s plenty of time to train the blood-sucking child in the ways of the supernatural world. Especially how to avoid the dangers of Vampire Slayers. Interestingly enough, a vampire can only give birth once in her immortal lifetime so she’d naturally want to relish her one and only Motherhood. Thankfully, it’s quite common for royal vampires to give birth to twins. Usually a boy and a girl.
