A mother polar bear and her cubs spend the first few months of the baby's life in a den. The den is usually a snow cave that the mother bear has built. During this time, the mother bear will nurse her cubs and teach them the basics of survival.
One of the most important things that mother polar bears teach their cubs is how to hunt. Polar bears are carnivores, and their diet consists mainly of seals. Mother bears teach their cubs how to stalk seals, how to break through the ice to reach them, and how to kill them.
Mother polar bears also teach their cubs how to survive in the harsh Arctic environment. They teach them how to build dens, how to find food, and how to avoid predators.
Finally, mother polar bears teach their cubs how to interact with other polar bears. Polar bears are social animals, and they live in groups called prides. Mother bears teach their cubs how to respect other bears, how to avoid conflict, and how to cooperate.
Cubs live with their mothers until they are two or three years old. By that time, they have learned everything they need to know to survive on their own. They will then leave their mothers and start their own lives.
