Berlin's baby polar bear will receive her name on Tuesday. /VCG

The fluffy cub stepped outside her den in March for the first time at Tierpark Zoo. /VCG Photo 

Born on December 1, 2018, the cub spent the first three and a half months of her life with her mother, Tonja. The mother and daughter share a strong bond, with Tonja never letting her cub out of her sight. /VCG Photo

Tonja lost three cubs in the past two years, and the tiny newborn is her new hope. Polar bear mortality rates are extremely high during the first three months of life. /VCG Photo
