Normal childbirth should be the right of the majority: not a chosen few. With the increasing risk of litigation, there is often a move to err on the side of caution and classify women as 'at risk' if they present with even a hint of a problem. This is a contested area, with wide interpretation of terminology and midwives need to be aware of the wide parameters of 'normal' in order to practise autonomously, effectively and safely. Soo Downe covers a wide variety of subjects, with international contributors giving the benefit of their expertise. This evidence-based text offers a widely applicable source book on multiple aspects of normal birth, proposing new approaches and paradigms for future research and practice.
