Childrearing expert Qiao Fangling uses a toy baby to teach grandmothers-to-be how to bathe an infant at a child parenting class in Shanghai, June 13, 2012. China will witness a baby boom in 2012 as it is the Year of the Dragon, which will exceed the number of available maternity nannies. Therefore, expectant parents who are bound to their workplace for most of the time will be forced to resort to their parents' help. To address this issue, some special childrearing classes were organized by the local women's federations for soon-to-be grandparents. [Photo/Xinhua]
