Elephant babies, or calves, are usually born at about 250 pounds and 3 feet tall. They're pretty clumsy for about 3 months after they're born, and have hardly any control over their trunks, which they often trip over. As if that doesn't make them enough of a handful, calves usually drink around 3 whole gallons of milk every day, a routine they sometimes keep for up to 10 years. That's a tall order for a mom of any species! While male elephants will grow to leave the herd after 12 years or so, females stay with their families for life.
