Three sweet Grizzly Bear cubs. Katmai National Park, Alaska 

If you are tired of human civilization I invite you to watch my newest video about three small bears and get their perspective.
They were waiting for their mother, who was fishing.
At the end her mother showed up and she was nurscing them. Such a cool scene.
Grizzly bear cubs will nurse for up to three years. Depending on when a grizzly mother bear wants to wean her cubs, a decision often made when she decides it’s time to mate again, she will keep producing milk for up to three years. However, grizzly cubs begin eating solid food from an early age and can very quickly become not dependent on mama’s milk.
