The polar bear cub, who has not yet been given a name, was born at Toronto Zoo in Canada in November and weighs 9.7lbs.
He is the only cub of the three-bear litter to have survived.
The cub has taken his first steps and is being looked after by zookeepers, as there are fears that his mother would reject him.
Polar bears are an endangered species and the World Wildlife Fund says that there are fewer than 25,000 left around the world.
