From a polar bear and her cubs in Canada to a dolphin and her calf in Japan, these animal moms are there to help when babies get hungry.

To celebrate the 25th anniversary of World Breastfeeding Week, we’ve collected incredible photos of 30 different animals nursing their offspring. World Breastfeeding Week is recognized every year from August 1 to 7 to encourage breastfeeding and improve the health of babies around the world.

Sneak a peek at these photos of animal mothers and their kin in these National Geographic Creative photos, which showcase the unique work of award-winning photographers and cinematographers.
