Six to eight weeks: The government shut down. Panda fans were bereft. For two weeks, the zoo was shuttered, and with it, the panda cam went dark. The cub grew from a 3-pound, pink, rodent-like creature to a 5-pound, black-and-white, cuddly-looking panda out of the public’s watchful gaze.

Almost three months: The cub takes her first steps — caught, adorably, on camera.

Three months: Introducing… Bao Bao. After more than 123,000 votes cast by members of the public, the cub was officially named. Disney fans’ choice of “Mulan,” one of five official options, lost out.

Five months: Bao Bao meets the adoring public for the first time. The National Zoo expected 10,000 visitors to the panda house during the three-day weekend when Bao Bao made her debut.

Bao Bao almost seemed bored at times on the first day members of the general public got a view of the most recent panda born at the National Zoo. She licked at a piece of bamboo and walked a bit and then promptly went back to sleep for much of the morning. She often slept 20 hours a day at that point. (Michael S.

Seven months: Bao Bao goes outside for the first time.
