Delayed / Optimal Cord Clamping

Waiting at least 30–60 seconds (often longer) after birth before clamping and cutting the umbilical cord.

← All topics

What it is

Instead of clamping the cord immediately after birth, the cord is left intact for a period of time so blood continues to transfer from the placenta to the baby. Many providers and guidelines now consider this the default rather than 'optional.'

Possible benefits

Possible risks

  • Slightly higher rates of newborn jaundice needing phototherapy in some studies[ACOG↗]
  • May need to be adjusted or skipped in specific emergencies (e.g., baby needs immediate resuscitation away from the parent)[ACOG↗]

Alternatives

  • Immediate cord clamping (historically routine; now less common for healthy births)[ACOG↗]
  • 'Wait for white' — waiting until the cord stops pulsating[Evidence Based Birth↗]
  • Cord milking in specific clinical situations, per provider judgment[ACOG↗]

Current evidence

ACOG and WHO recommend delaying cord clamping for at least 30–60 seconds for vigorous term and preterm infants when feasible. Evidence Based Birth has an in-depth plain-language summary. Confirm current recommendations with your provider.

Where the evidence is clear · where people may choose differently

For most topics, guidelines from ACOG, WHO, and other major bodies broadly agree on the core safety points (when to act in an emergency, informed-consent standards, monitoring baselines). Where reasonable people — and even guidelines — differ tends to be around thresholds (when to start or stop something), preferences (comfort, environment, support), and values (how you weigh small risks against benefits). Use the questions below to explore those pieces with your care team.

Questions to ask your care team

  • ?Is delayed cord clamping standard practice here?
  • ?How long do you typically wait before clamping?
  • ?If baby needs help at birth, how is cord clamping handled?
  • ?Can my partner still cut the cord after the delay?

Universal questions (works for any decision)

A short BRAIN-style set you can bring to any conversation about interventions, monitoring, or care decisions.

  • ?Why are you recommending this now — is it urgent, routine, or optional?
  • ?What happens if we wait an hour (or longer) before deciding?
  • ?What signs would tell us this is working — or that we need to change course?
  • ?What are the alternatives, including doing nothing?
  • ?What would you recommend if this were your family?
  • ?What would change your recommendation?
