Video of polar bear cub sleeping and dreaming at Columbus Zoo & Aquarium

COLUMBUS, OHIO (FOX 13) - Video of a polar bear cub sleeping in a crib is the most adorable thing you'll see all day. The video of the 5-week-old cub, released by the Columbus Zoo and Aquarium, shows her moving around, making noises, and even sometimes, appearing to dream as she sleeps.

She's just over 4 pounds and her eyes are starting to open. According to the Columbus Zoo and Aquarium's Facebook post, "the care staff says the sound that she makes in the video is of contentment."

The zoo said the mother of the newborn cub stopped caring for her cub, so the Animal Care staff intervened and began to hand-rear her.

She is healthy, though, and the staff continues to take it one day at at time to tend to her needs.
