A female panda has taken on the role as mother and nurser for seven cubs in southwest China's Chengdu Panda Base, as their birth mothers are engaged in artificial insemination.
Yaya, now 22-year-old, almost 90 years of age in human terms, has been breastfeeding and taking care of seven cubs for nearly a year.
She has continually given great care and affection to cubs as she herself has given birth to 13 babies, of whom 12 survived.
The loving mother always encourages her cubs to find on their own apples thrown in by the keepers from time to time.
The baby pandas will be weaned off in four months, when they turn two years old.
Yaya was named after the 1990 Asian Games ("Ya Yun" in Chinese) in Beijing, as she was born days just before its opening.
The birth mothers of the cubs, chosen to artificially conceive in their mating season between March and May, are expected to give birth between August and October this year.
Giant pandas reach sexual maturity between the ages of four and eight, and may be reproductive until age 20.
