They start to crawl, grow teeth, and may even begin to mouth bamboo-signaling that these cubs are ready for the next phase of life. Finally, around three or four months old, their external genitalia begins to develop, and pandas can finally defecate and urinate on their own. “As she starts to leave more, you know that the cub is able to regulate its body temperature and is okay with being alone for periods of time,” Thompson says.Īt six weeks, they start to open their eyes, and by two months, their ear canals are open. Mei Xiang’s newborn gained about 50 percent of its bodyweight between its first two weigh-ins, which took place less than a week apart.Īfter about a month of holding their babies all day every day, mothers start to experiment with putting their cubs on the ground and leaving the den briefly for food and water breaks. “Once they’re out and they’ve got mom taking care of them and feeding them so much, they do start to grow really fast,” Thompson says. Newborn pandas also gain weight at a rapid pace, suckling their mother’s milk up to 14 times a day. Within about three weeks, their fur is all filled in. Within 48 hours, white fur begins covering their pink skin, followed by the black markings around their eyes and on their bodies. Though they don’t develop much inside the womb, panda newborns make up for it quickly. In captivity, scientists step in to care for the neglected cub and even attempt to swap the cubs to ensure both get their mother’s attention and milk. Motherhood is such a demanding job that pandas who give birth to twins can often only take care of one-and are forced to abandon the other. In these early weeks, panda mothers don’t leave their cubs, even when they need to eat or drink. Instead, the mother has to take care of both, cradling her cubs to keep them warm and rubbing their bellies to stimulate the muscles to release urine and feces. They are so helpless that they can’t regulate their body temperatures or even excrete waste on their own in the first weeks of life. Panda newborns rely on their mother for milk and protection because they cannot see, hear, or crawl.

Learn about giant pandas and how their diet shapes their lives. They spend nearly every waking moment eating bamboo. Giant pandas' habitat in the wild today is limited to the mountains of China, but their appetite remains unlimited. Rather than expend the enormous amounts of energy needed to grow a fetus, female pandas can focus on developing the high-fat milk that will help their cubs grow outside of the womb. The short gestation likely has to do with the bamboo that makes up most of the bear’s diet, says Laurie Thompson, assistant curator of giant pandas at the National Zoo. The study found that other bear species gestate for two months and are born with mature skeletons, while newborn pandas gestate for only a month and their skeletons emerge comparatively “undercooked,” according to the study’s authors. In December 2019, a study published in the Journal of Anatomy examined the skeletal structures of giant pandas and their bear cousins, which also tend to be born small relative to their mothers. Researchers don’t know for sure why pandas are born so tiny. Red kangaroos, for example, are born at 1/100,000th the weight of their mothers. Only marsupials emerge smaller‚ and that’s because their babies get to hole up in their mothers’ pouches to finish developing. This places them among the smallest newborns compared to their mother of any mammal: Human mothers are only about 20 times heavier than their babies, and killer whales are 50 times heavier. Weighing between three and five ounces, newborn pandas are 1/900th the weight of their mother. Pandas are born fragile and underdeveloped. So how do they grow into the cuddly furballs that humans are hardwired to love? Here’s a look at how baby pandas grow up. Rather than sporting their iconic black-and-white markings, pandas emerge from their mothers as pink, wrinkly, blind, squealing creatures roughly the size of a stick of butter. Newborn giant pandas are almost completely unrecognizable. Not only are mothers incredibly protective of the cubs at this age, but pandas are also born without genitalia. Genetic tests are the only way to discern the sex of a panda cub in the earliest weeks of its life.

The genetic testing was conducted at the still-unnamed newborn’s first veterinary exam in September, a full month after its birth on August 21. Six weeks after giant panda Mei Xiang gave birth in Washington, D.C., Smithsonian’s National Zoo revealed the gender of the newborn cub-not with a colored cake or fireworks, but with an adorable photo and the results of a genetic test.
