A behind the scenes view of the work of the intensive care neonatal unit at Liverpool Women's Hospital.

It's every parent's worst nightmare: a birth that goes wrong or a baby born early. This three-part series looks at the one in ten cases where things don't go to plan and a baby is left teetering between life and death. The intensive care unit at Liverpool Women's Hospital cares for 1,000 sick and premature babies a year and while the majority of babies survive, there are also many stories of tragic and heart-wrenching loss.—Lynn Alleway
