Go Little Sloth Star! | The Sloth Conservation Foundation

A baby sloth is born with its eyes open, claws sharp, and teeth fully formed. Most newborn sloths weigh between 300 to 500 grams (about 10 to 17 ounces), and three-fingered infants are usually smaller than two-fingered infants. Immediately after birth, the baby will instinctively crawl up toward the safety of its mother’s chest and cling to her fur. Once there, the baby will hold on for the next six months, nursing small amounts of milk throughout the day. As early as one week old, baby sloths will begin sampling leaves from around their mother’s mouth in addition to drinking milk.
