The National Zoo's panda cub Be iBei is growing up so fast.
On Monday, the Zoo released video of the cub climbing a tree - with the help of mom Mei Xiang who never left his side.
In the video, the baby makes his way down the tree while mom's outstretched arms are waiting as a safety net just in case of a slip.
Lots of milestones this year for Bei Bei! Last month he played in the snow for the first time: http://www.fox5dc.com/news/79650240-story
