But when she was just a week old, her mother Aurora, stopped caring for her.
Experts at Columbus Zoo and Aquarium in Ohio had no choice but to remove the cub from her mum's enclosure.
For the past five weeks, she has been hand-reared and is doing well.
She's fed with a specially made polar bear formula, and has gone from weighing half a pound to almost seven, and has grown to 17 inches long.
Like all little ones, she's teething at the moment.
Her dedicated carers have been helping her out by letting her gnaw on frozen human baby teething toys.
They uploaded this heart-warming video to their Facebook page to show the six-week-old's progress.
Adorably, she even cuddles up to a stuffed polar bear toy.
