This sleepy little polar bear cub is nearly six weeks old.

She's being cared for by staff at the Columbus Zoo in the US, because her mum, named Aurora, stopped looking after her.

The little cutie doesn't have a name yet and weighs just 1.5 pounds.

At the moment she's enjoying her sleeps with her teddy, and making lots of happy noises as she dreams.
