Lincoln Park Zoo welcomes baby sloth

CHICAGO (WLS) -- Lincoln Park Zoo is welcoming a newborn arrival of the two-toed variety.

A Hoffman's two-toed sloth baby was born last week at the zoo's small mammal and reptile exhibit.

Zookeepers aren't sure of the baby's size or sex because it clings so closely to its mother.

Visitors are warned to be patient. The sloths do not move around much during the day and when they do, they move very slowly.
