A mother bear in Canada is very kind. She is five years old. She has a baby bear that is not hers.
This is a big surprise. It is near a town. The mother bear has one baby. Then she finds another baby.
This baby bear is alone. It lost its own mother. Mother bears like to help babies.
This help is not common. It is very rare. Scientists watch the mother bear. They have a special tag on her. They want to learn more.
It is hard for baby bears. A mother helps them live. She teaches them to find food. She helps them go places. This helps all polar bears.
