For many years, immediate cord clamping has been treated as routine practice, yet growing evidence tells a very different story. In this article, Dr Sara Wickham explores the research behind what is often called “optimal” or delayed cord clamping, highlighting how leaving the cord intact for even a few minutes can significantly benefit a baby’s transition to life outside the womb. Drawing on systematic reviews and recent studies, she challenges long-held assumptions and brings attention back to physiology, showing that what has been labelled as “delayed” is, in fact, the body’s natural process, one that supports better blood volume, iron stores, and overall newborn health.
What's the evidence for optimal cord clamping? Dr Sara Wickham shares a summary of the research in this area.
