It's nine in the morning, and Dr. Huang Libin begins his rounds at his hospital's pediatrics department. It's a taxing job, but he can get off work only after noontime the next day.
Huang is a pediatrician at one of the largest hospitals in southern China. Here there are less than 30 doctors serving the flood of parents and their children.
"It's very difficult to schedule work shifts, especially when the female doctors are on maternity leave to have their second babies. A whole day's duty is from 8:00 am to midnight the next day. We male doctors have to be on six to eight shifts like this every month."
A year ago, China formally introduced the two-child policy nationwide, ending decades of the one-child rule. Today, that policy's effects are gradually being felt.
In 2016, around 18 million babies were born in China, the highest number since the 2000. And 45 percent of them are the second in family.
