Smithsonian National Zoo's 3-week-old panda cub gets adorable 1st checkup

The giant panda's cub received its first neonatal exam.

This panda cub doesn't have a name yet, but it's already stealing our hearts!

The Smithsonian's National Zoo delivered an update on giant panda Mei Xiang's 3-week-old cub Monday and we just can't get enough.

Mei Xiang gave birth at 6:35 p.m. on Aug. 21 and has been caring for her cub ever since.

But when Mei Xiang left her den to eat, the zoo's team was able to retrieve the cub for its first neonatal exam, according to a press release from the National Zoo.

"We are encouraged to see that our young panda appears to be healthy and vibrant," the National Zoo wrote on its website.

The cub's sex has not yet been determined, but it weighs less than 1 1/2 pounds.

"During a typical cub exam, the panda team charts the cub’s growth by obtaining its weight and measurements. In the near future, the Zoo’s veterinary team will join us to perform a full medical exam on the cub," the team added.

The zoo has been releasing #PandaCubdates on its website and social media platforms.

They also have live "Panda Cams" where you can check in on Tian Tian and Mei Xiang.

If you're luckily enough you may even catch a glimpse of the 3-week-old cub!
