China abandoned its decades-old one-child policy more than two years ago. Since then, all Chinese couples have been allowed to have two children. This was largely to slow the aging of the population. But, so far results have been mixed. Our Jane Kiyo visited one of Beijing's largest maternity hospitals to find out why.

JANE KIYO BEIJING It's been almost three years since Chinese couples were allowed to have two children. The scrapping of the decades-old one-child policy was meant to produce a balanced population. An ageing population, which China currently faces, means a shrinking workforce, which could threaten the economy. Now we are here at one of Beijing's biggest maternity hospitals to find out if there's been any changes after the one-child policy was abolished.

JANE KIYO BEIJING The hospital records at least 15,000 births a year. This is also because it controls the number of patients for safety reasons. Doctors here tell us more than 40% of the women here are giving birth to their second child.

DR. WANG XIN DIRECTOR, BEIJING OBSTETRICS AND GYNECOLOGICAL HOSPITAL "Since the government introduced the two-child policy, there's been an increase in the number of women giving birth to a second children. But there are also a number of challenges, including high-risk pregnancies caused by different factors. For example, some women have had previous operations. Others are now much older, and so giving birth is risky for them."

JANE KIYO BEIJING Health officials had hoped the two-child policy would produce a baby boom with 20 million births per year. But this hasn't happened. Last year there were only 17 million. Couples say raising children is too expensive. Others have become accustomed to having just one child.

ZHANG JINGJING EXPECTING MOTHER "We've always wanted a second child but we couldn't because neither I nor my husband is an only child in our families. So we had to wait until the policy was changed. There's always pressure to raise children but we are willing to pay more for them."

KONG XIAOWEI NEW MOTHER "I am 40 years old now. I wanted to have a second child because I wanted my first born to have company."

JANE KIYO BEIJING Experts say it's still too early to gauge the impact of the two-child policy, but they hope, like Zhang Jingjing, that more Chinese couples can embrace it. Jane Kiyo, CGTN, Beijing, China.
