A baby polar bear is called a cub. Typically, polar bears give birth to one to three cubs at a time, and these adorable little ones are born weighing about 1.5 pounds (0.68 kg) and are completely helpless at birth. Polar bear cubs usually stay with their mother for about two to three years until they are ready to fend for themselves.
The term ‘cub’ is commonly used for the young of many species of bears, not just polar bears. The bond between a mother polar bear and her cubs is crucial for the cubs’ survival, as they depend on their mother’s milk and protection during their early life stages in the harsh Arctic environment.
