Exhausted moms turn to baby sleep consultants

WUHAN - Late at night, an exhausted mother gets up once again to attend to her screaming baby. She rocks, feeds and sings him to sleep before sneaking away, but she knows it will not be long before she has to return.

Liu Dan is familiar with this scenario. During the day, she works at a broadcasting station in Hangzhou city, and has only slept three or four hours each night since her son was born.

A well-known supplement in China advertises that it can help people "sleep like a baby", but Liu scoffs at the tagline.
