A baby deer is called a fawn. This is especially true for a baby deer not yet weaned from its mother. A whitetail deer fawn is born with white spots that it loses before it is weaned.
The newborn fawn is odorless so that predators are not alerted to its presence. The doe typically stays away from her fawn as much as she can for the first few days of the fawn's life in order to prevent her smell from rubbing off on it. In addition to single births, twin fawn births are also common. On rare occasions, triplets are born to the same doe.
