Our panda cubs are doing well but the panda team had a challenging night. When they tried to swap the cubs at 11p.m., Mei Xiang would not set down the cub she had in her possession. Consequently, the panda team cared for the smaller cub throughout the night until 7:05 a.m. when they successfully swapped the cubs. The panda team supplemented the smaller cub with formula by bottle feeding. They were concerned that the smaller cub was not getting enough volume so they moved to tube feeding which went well and quickly. Our goal is for each cub to spend an equal amount of time with their mother. As we've stated, the newborn cubs are vulnerable and this first week is incredibly important and the risk remains high. Our team is doing great work around the clock and we'll continue to keep you posted. Follow #PandaStory on Instagram (@SmithsonianZoo) and Twitter (@NationalZoo) fort the latest.
