How long do polar bears stay with their mate?

How many babies do polar bears have?
In the middle of winter in some of the coldest places on Earth, female polar bears give birth to cubs. Litter size is most commonly two cubs, but sometimes litters can be one, three, or, very rarely, four cubs.

How fast do polar bears reproduce?
every three years
If cubs survive, they are (in most areas) weaned in the spring around the age of two years. Once cubs have been weaned, the mother will mate again. This high maternal investment means that female polar bears usually reproduce every three years, or less often, depending on cub survival.
How do polar bears have babies?

Do polar bears eat their babies?
Scientists believe that polar bears eat cubs in the late summer and autumn, when seals, their typical prey, are at sea and less available. “One of the only things that’s left to eat is, in fact, cubs of various ages,” says Ian Stirling, a biologist at the University of Alberta and Environment Canada.
