Delayed Cord Clamping: What It Is and Why It's Become Standard
Waiting a short while before clamping the umbilical cord is now widely recommended. Here's what delayed cord clamping does, when it's used, and what to ask.

If "delayed cord clamping" is on the birth-plan template you downloaded, you may be wondering whether it's something you need to fight for. Good news: in many hospitals it's already routine, it's recommended by major obstetric organizations, and it's usually compatible with the rest of your plans. Here's what it actually means and what's worth knowing.
What Delayed Cord Clamping Is
When your baby is born, they're still connected to the placenta by the umbilical cord, and that cord still has blood flowing through it. For decades, the cord was clamped and cut almost immediately. Delayed cord clamping (often shortened to DCC) simply means waiting a short while — commonly at least 30 to 60 seconds, sometimes a few minutes — before clamping.
During that brief wait, more of the blood in the cord and placenta transfers into your baby. That extra blood carries red blood cells and iron, giving your baby a little boost as they make the transition to life outside the womb.
It's a small change in timing with a real, if modest, payoff.
Why It's Now Recommended
The shift toward DCC happened because the evidence accumulated in its favor. Major obstetric guidance now recommends delayed clamping for vigorous babies, both full-term and premature.
The documented benefits include:
For term babies: better iron stores in the first months of life, which supports healthy development (iron deficiency in infancy is something worth avoiding).
For preterm babies: a reduced need for blood transfusion and a lower risk of certain complications of prematurity.
These are meaningful but measured benefits — DCC is a good default, not a miracle. The reason it's become standard is that the upside is real and the downside, in most situations, is minimal.
When It Isn't Done
Delayed cord clamping is the usual plan, but there are situations where the team will clamp sooner, and those exceptions exist for good reasons:
Your baby needs immediate help. If a baby is not breathing well or needs resuscitation right away, getting them to the warmer for care takes priority over the wait. (Some hospitals can do certain newborn care with the cord intact, but not all.)
You're bleeding heavily. If you have significant hemorrhage, the team may need to move quickly through the delivery of the placenta.
Certain medical situations with you or your baby make earlier clamping the safer choice.
In other words, immediate clamping isn't the team ignoring your wishes — it's them responding to something that needs faster attention. If that happens, it's a sign they're prioritizing safety, and the brief loss of the DCC benefit is a worthwhile trade for getting your baby (or you) the care needed.
A note for cesareans: delayed cord clamping can often be done during a C-section too, though it depends on the situation and the hospital's practice. It's a reasonable thing to ask about if you're planning a cesarean.
Do You Need to Request It?
Often, no — because it's frequently already the default at hospitals that follow current guidance. But there's no harm in confirming. A simple, low-key way to raise it:
Mention it in your birth preferences: "I'd like delayed cord clamping if my baby is doing well."
Ask on a prenatal visit or hospital tour whether it's their routine practice.
Phrasing it as "if my baby is doing well" is helpful, because it signals you understand the exceptions and trust the team to clamp early if your baby needs immediate care. That framing tends to land better than treating DCC as non-negotiable — and it's also just the accurate way to think about it.
One more practical point: delayed cord clamping is generally compatible with immediate skin-to-skin. Your baby can often be placed on you (or just below, depending on the setup) during the wait, so you don't have to choose between the two.
The Reframe
Delayed cord clamping is a brief, evidence-backed wait that lets a little more blood reach your baby — better iron stores for term babies, fewer complications for preterm ones. It's now widely recommended and often already routine, so in many places you won't have to advocate hard for it. Add it to your preferences with the sensible caveat — "if my baby is doing well" — and trust your team to clamp sooner only if your baby or you need quicker care. It's a nice default to want, and an easy one to be flexible about.
