China's only children are often spoiled "little emperors"
Officials in Shanghai are urging parents to have a second child, the first time in decades the government has pushed for more babies.
A public information campaign has been launched to highlight exemptions to the country's one-child policy.
Couples who were both only children, which includes most of the city's newly-weds, are allowed a second child.
The move comes as China's most populous city becomes richer and older, with the number of retired residents soaring.
"Shanghai's over-60 population already exceeds three million, or 21.6% of registered residents," said Zhang Meixin, a spokesman for the city's Municipal Population and Family Planning Commission.
