It was filmed over six months at busy labour units at St Mary’s Hospital in Manchester and at Arrowe Park, Wirral.
The programme aims to give viewers an insight into the daily struggles that midwives face.
With the UK in the midst of the biggest baby boom in 40 years, and the NHS suffering constant cutbacks, the midwives are shown juggling parents’ needs and NHS demands.
Each episode attempts to focus on a different element of a midwife’s career.
These include episodes on how the midwives cope with working in a high-risk unit under constant pressure, and another on student midwives and the tough training they are required to complete.
The midwives deal with mothers in a range of situations and follow them as they deal with a number of challenging dilemmas, but the series also shows the more rewarding aspects of being a midwife.
The programme follows in the footsteps of the recent success of Call the Midwife, based on the memoirs of Jennifer Worth.
The series saw over 10 million viewers watch the portrayal of midwives working in 1950s East London.
It is the BBC’s most successful new drama since the ratings system begun 11 years ago, and a second series has already been commissioned, which is expected to air in 2013.
The first episode of The Midwives, called Delivering Under Pressure, starts tonight on BBC2 at 9pm, and will be available on iPlayer shortly afterwards.
