It takes a lot of work to bring a panda cub into the world. They are born with delicate pink skin, they're unable to see, unable to walk--and even unable to go to the bathroom without help! It's so much work that panda mamas can only take care of one cub at a time. So when Zoo Atlanta's beloved giant panda, Lun Lun, surprised everyone by having twins, the zoo staff had to pitch in. They made a plan to share parenting duties with Lun Lun. Every few hours the zoo staff swapped the cubs between Lun Lun and their workroom to make sure the cubs got equal time with mom. It was hard work, and Lun Lun didn't even know she had twins! The cubs ate and slept, opened their eyes, and grew beautiful black and white coats. Fans watching around the world submitted name ideas for the cubs. Everyone cheered as the cubs took their first steps. As the cubs grew larger and more independent, excitement grew about their upcoming reunion. Would Lun Lun accept them when she finally met them both? Luckily for Lun Lun, motherhood came naturally.
