A baby elephant is called a calf. It weighs about 250 pounds at birth and stands about three feet tall. Calves can't see very well at first, but they can recognize their mothers by touch, scent, and sound. At first, baby elephants don't really know what to do with their trunks. They swing them to and fro and sometimes even step on them. They will suck their trunk just as a human baby might suck its thumb.
