Helping other women give birth is very much a part of the daily routine for midwife Noella Tsang.
But she was taken by surprise when her own baby arrived four days early to become Hong Kong's first birth of 2011 on the stroke of midnight.
Doctors at Queen Elizabeth Hospital in Yau Ma Tei confirmed that Tsang's boy - who has not yet been given a name - was the first of the year.
Her husband, Ivan Tsang, a doctor who works on the internal medicine wards of Caritas Medical Centre in Sham Shui Po, captured the happy moment on a video camera.
'Sometimes I didn't know if I should film my wife or the baby. It's magical. The two of us went into the hospital, and three of us will be leaving it. I can't describe this feeling,' he said.
The baby, which weighed in at 2.71kg, was expected on January 5.
As both parents are in the medical profession, they had considered theirs and the baby's needs for the big day way ahead of time.
