What You Should Know About Delayed Cord Clamping & the White Cord Trend

The Midwives of New Jersey are big believers in delayed cord clamping (dcc). We practice it at every birth where it is safe to do so, and we have for years. But lately, more and more of our clients have been asking us about a newer trend making the rounds on social media: waiting until the umbilical cord turns completely white before clamping it. Enough women have brought it up that we believe it is worth explaining.

As Lisa Lederer, CNM & President of Midwives of NJ, puts it, “You really have to look at the actual physiology and what’s actually happening and why we do what we do.”

Where Delayed Cord Clamping Originated

To understand why the white cord trend is inaccurate, it helps to remember why delayed umbilical cord clamping after birth mattered in the first place. So what is delayed cord clamping, exactly? Simply put, it means waiting to clamp and cut the cord so the baby can receive the blood still in the placenta. For decades, hospital birth followed a routine that had very little to do with the baby’s needs. The baby would be delivered and the cord would be clamped and cut right away. Before the baby had moved or had taken a single breath, the cord was already cut and the baby was handed off to the nursery staff.

Midwives pushed back against that practice, and for good reason. At the moment of birth, a significant amount of your baby’s blood is still in the placenta and the cord. Delaying the clamp gives that umbilical cord blood optimal time to reach your baby.

This is called placental transfusion, and it is one of the beautiful ways a woman’s body has been perfectly designed for birth. This is one of the key benefits of delayed cord clamping: it gives your baby blood volume, iron, stem cells, and oxygen-carrying red blood cells at the exact moment they are making the enormous transition from life in the womb to breathing air. As for how long to delay cord clamping, the American College of Obstetricians and Gynecologists recommend a delay of at least 30–60 seconds after birth for vigorous term infants and preterm infants, a recommendation supported by randomized controlled trials (ACOG: Delayed Cord Clamping After Birth).

What Actually Happens in Those First Breaths

Before your baby takes that first deep breath and cries, their lungs are essentially closed off. The blood that will eventually flow through them has nowhere to go yet. Then the baby breathes, oxygen reaches the lungs, and the blood vessels open.

Think of it like a dam. The blood from the placenta is sitting there, waiting, and when the baby takes those first deep breaths, the dam opens and the blood flows in. It’s not a long, drawn-out process. The blood moves into the lung fields, and that’s all the baby can take. Once that has happened, the transfusion your baby needs is complete. That is when your Midwives clamp and cut the cord and move on to the next part of your birth.

What a White Cord Actually Means

Understanding what happens to the umbilical cord after birth is the key to this whole conversation. A white cord is not the marker of a completed transfusion. The transfusion is usually finished well before the cord changes color. When the cord turns white, it simply means the blood vessels inside have emptied and closed down, leaving the pale, jelly-like tissue of the cord visible. That process can take much longer than the transfusion itself.

The key to understand is that transfusion of blood isn’t over a long period of time. The cord does not need to turn white for that to happen. Waiting for white often means waiting past the point of any real benefit to your baby. Your baby has already received what the placenta had to give, and the extra minutes don’t add anything more for them.

Dangers of Over-Delaying Cord Clamping

Some women assume that if a little delay is good, a longer delay must be even better, and we’ve even been asked about delayed cord clamping for 1 hour. But there are real delayed cord clamping risks when the wait goes too long. We understand that instinct, and we have honored it. When clients asked, we delayed clamping for as long as possible, sometimes 15 or 20 minutes. But in so doing we’ve seen an increase in very significant postpartum hemorrhages, which can be life threatening for a new mother.

After your baby is born, your body still has one more important job to do. Your uterus needs to contract firmly, release the placenta, and clamp down to control bleeding. When that third stage of labor is drawn out without a good reason, it can interfere with what your body is working to accomplish. Protecting the mother is every bit as important as protecting the baby. A mother and child both deserve our full attention in those first minutes.

What Your Midwives Are Actually Watching For

This is exactly why your Midwives aren’t watching for a color change. We are watching your body, your baby and the physiology happening in real time. We are watching how your baby is breathing and transitioning, how your uterus is responding, how much you are bleeding, and how you are feeling as you meet your baby for the first time.

Every birth is different, and knowing when to cut the umbilical cord is a clinical judgment made in the moment. It’s not black or white. That judgment comes from training, from experience, and from having been present at thousands of births. It is part of what it means to be with you throughout your labor and birth.

Talk It Through Before You Add It to Your Birth Plan

We love that women are educating themselves and coming to their appointments with questions. We believe women can be trusted to make the best decisions for themselves and their families when given reliable, non-biased information. That is exactly why we want to have this conversation with you, rather than leave it to a social media feed.

So before adding an online birth trend to your birth plan, talk it through with your Midwives first. That way you know exactly what you are asking for, why you are asking for it, and why timing matters far more than what the cord looks like when it comes to cutting the umbilical cord. Our job is to educate, encourage, and support you, and that includes helping you separate what the physiology actually shows from from a trendy birth plan ask.
