Bei Bei The Baby PandaWaves To Adoring Fans, Panda-monium Ensues

Bei Bei, the insanely adorable giant panda cub at the National Zoo in Washington, D.C., was without a doubt the most important birth of 2015. (Sorry, Princess Charlotte .)

But in order to provide the First Family of Cuteness some peace and quiet, the zoo's panda habitat has been closed  since August, depriving eager fans of a good look at the young cub.

Thankfully, keeper Marty Dearie wrote in December that Bei Bei had "grown exponentially over the last few months" -- weighing an impressive 16 pounds as of Dec. 7  -- which means the 5-month-old is finally ready to make his public debut on Jan. 16. 

And from the looks of it, he's a natural:

Pandas have a notoriously difficult time reproducing , which is one reason for the animals' endangered status. 

Bei Bei and a twin brother, who died shortly after birth, were the result of artificial insemination . Bei Bei's parents, Tian Tian and Mei Xiang, also live at the zoo with their 2-year-old daughter Bao Bao, also the result of artificial insemination. 

Bei Bei, who was born Aug. 22, is now thriving, which marks a huge success for the zoo -- and a victory for anyone with a soul: 

The zoo has been introducing the baby cub to crowds incrementally, including a Jan. 7 checkup that was open to lucky members of the press. 

And it's no surprise the little star is ready for the spotlight. 

In December, Bei Bei showed the world just how chill he is by snoozing through his media debut . His DGAF attitude was so strong, he even left tiny drool stains on the table:

Today, Bei Bei is bigger than either of his older siblings were at his age. (His 10-year-old brother, Tai Shan, now lives in China .)

According to the zoo's periodic Giant Panda Bulletin (what a time to be alive), the young cub spends most of his time sleeping, nursing or learning how to walk . And his chubby baby face is just too much to handle: 

Judging by his older sister -- whom keeper Nicole MacCorkle and biologist Laurie Thompson described as "a playful adolescent " in a December update -- Bei Bei is probably only going to get cuter.

When it comes to the inevitable cuteness overload, we're just going to have to grin and bear it.
