( CNN ) -- Very few pandas are born each year , but even fewer of the fragile cubs stay alive . That 's why zookeepers say it 's a `` miracle '' after a panda gave birth to a healthy set of triplets , who have now survived over two weeks and are reportedly doing well . The cubs , which weighed 83 grams , 90 grams , and 122 grams , respectively , at birth , are thought to be the only living panda triplets in the world . The 12-year-old mother , Juxiao ( whose name means `` chrysanthemum smile '' ) gave birth to the adorable cubs on July 29 in China 's Chimelong Safari Park in the southern city of Guangzhou . The delivery took four hours , said Dong Guixin , the manager of the park . `` After nearly half a month under the care of the mother , the babies are very healthy , '' China Daily reported Dong as saying . `` They now weigh nearly two times what they did when they were born ... It was a miracle for us and the births exceeded our expectations . '' The new trio are now with their mother and are being cared for by a team of feeders , he said . Pandas are known for having very low survival rates . According to the Chengdu Research Base for Giant Panda Breeding , only one-third to one-half of pandas born in Chinese captivity manage to survive past infancy . In 1999 , another set of giant panda triplets was born in China , but one died after three days . In the next few weeks , another little panda could enter the world : Tian Tian , a panda living in Scotland 's Edinburgh Zoo , is suspected to be pregnant and may give birth before the end of August . Thanks to science , there are more baby pandas .
