World's only giant panda triplets thrive in China

The world's only surviving giant panda triplets are doing well as they turn 100 days old.

The cubs will be displayed to visitors in China for limited periods.

Each weighs only about 11 pounds, but that's up from three and a half ounces at birth. They started teething at around 80 days old and have two small teeth each.

They are also taking turns living with their mother. Officials say the cubs are doing very well.
