0 year old

A newborn person that has just begun to explore the world. Some talk, some don't. The development of the human body also happens the fastest in this time, so the baby's age is mostly counted in months or even weeks in this time. People aged this young have no real consciousness, but show human characteristics. Not much to say about people aged 0.
