The Denver Zoo’s sloth parents Charlotte and Elliot gained a new family member Friday with the birth of their fourth baby sloth.

The Linne’s two-toed sloth pup is healthy, strong and “nursing like a pro,” Denver Zoo officials wrote in a Facebook post.

Zoo-goers may catch a glimpse of mom Charlotte and her pup in their treetop habitat in the Tropical Discovery building.

Sloth gestation lasts 10 months, and sloths give birth to one baby in the trees, according to the Denver Zoo.

Newborn sloths are 10 inches long and weigh up to 13 ounces. The baby climbs onto its mother’s belly and clings while nursing for up to five weeks.

Sloth pups stay with their moms for nine months before moving out on their own, according to the zoo.

Zoo officials still need to perform a DNA test to determine the baby’s sex, and its name is also still being decided.
