Delayed Cord Clamping & Cord Blood Banking: What Every Parent Should Know
When your baby is born, there is a brief but powerful moment that often gets overlooked.
Before the cord is clamped and cut, your baby is still receiving blood, oxygen, and vital nutrients from the placenta. This moment, and how long you allow it to continue, can have a meaningful impact on your baby’s transition into the world.
Let’s break down what cord clamping is, why timing matters, and what to consider when it comes to cord blood banking.
What Is Cord Clamping?
After birth, the umbilical cord is clamped to stop blood flow from the placenta to your baby, and then it is cut.
There are two main approaches:
Immediate or early cord clamping (ICC)
The cord is clamped within about 30 to 60 seconds after birth.
Delayed cord clamping (DCC)
The cord is clamped after more time has passed. This can mean waiting at least 60 to 90 seconds, several minutes, or until the cord stops pulsating or turns white.
During delayed cord clamping, baby is typically placed skin-to-skin on your chest, allowing for bonding while this natural transfer continues.
Why Timing Matters
At the moment your baby is born, a significant portion of their blood is still in the placenta.
About one third of your baby’s blood volume is outside their body at birth.
With immediate clamping, a large portion of that blood remains in the placenta.
With delayed cord clamping, more of that blood transfers into your baby.
This additional blood includes:
Red blood cells that carry oxygen
Iron stores that support development
Stem cells that play a role in growth and healing
It also helps support lung function as your baby begins to breathe on their own.
The Benefits of Delayed Cord Clamping
Research continues to support delayed cord clamping as a simple, evidence-based practice with real benefits.
For full-term babies, delayed clamping is associated with:
Higher hemoglobin levels at birth
Increased iron stores in the first months of life
Higher blood volume, which supports circulation and oxygenation
Potential benefits for brain development
For preterm babies, benefits can be even more significant, including improved survival and reduced need for transfusions.
Importantly, research has not shown an increased risk of postpartum hemorrhage for the birthing parent.
What About Jaundice?
You may hear concerns that delayed cord clamping increases the risk of jaundice.
Current evidence does not support this concern.
Most high-quality studies have not found an increased risk of jaundice in babies who receive delayed cord clamping.
What Is Standard Practice?
In many Southern California hospitals, standard delayed cord clamping used to be around 60 seconds.
More recently, this has shifted closer to 90 seconds.
This is a step in the right direction.
However, many families choose to wait longer when possible, such as until the cord stops pulsating, to allow for a more complete transfer of blood.
Can You Request Longer Delayed Cord Clamping?
Yes.
This is something you can absolutely discuss with your provider ahead of time.
A helpful question to ask is:
“What is your standard practice for cord clamping, and can we wait until the cord stops pulsating?”
Unless there is a medical reason to intervene, many providers are open to supporting longer delays when families express this preference.
What Is Cord Blood Banking?
Cord blood banking involves collecting blood from the umbilical cord after it is clamped.
This blood contains stem cells, which can be used in certain medical treatments.
There are two main types of cord blood banking.
Private Cord Blood Banking
Private banking stores your baby’s cord blood for your family’s potential future use.
It is often marketed as a one-time opportunity to preserve stem cells.
Things to consider:
It can cost $1,000 to $3,000 upfront, plus ongoing storage fees
It is typically not covered by insurance
Delayed cord clamping beyond about one minute is often not possible if collecting cord blood
Many professional organizations do not recommend routine private banking
There are also limitations in how often privately banked cord blood is actually used.
Public Cord Blood Donation
Public banking allows you to donate your baby’s cord blood to help others.
This option:
Is free for families
Supports patients in need of stem cell transplants
Is supported by many major medical organizations
Availability depends on your birth location, as not all hospitals offer collection.
How to Decide What’s Right for You
This decision is personal, and there is no one-size-fits-all answer.
Some families prioritize maximizing delayed cord clamping.
Others feel strongly about cord blood storage or donation.
What matters most is that you:
Understand your options
Ask questions ahead of time
Make a decision that aligns with your values
How Doulas Support These Decisions
This is one of those moments in birth where preparation makes a big difference.
Our doulas help families:
Understand the benefits and trade-offs of each option
Have informed conversations with their providers
Include preferences like delayed cord clamping in their birth plan
Advocate for their choices in the birth space
Because small moments like these can have a lasting impact.
Final Thoughts
Delayed cord clamping is a simple, evidence-based practice that supports your baby’s transition into the world.
While standard practices are slowly improving, families still have the opportunity to ask for more time and make informed choices.
You deserve to understand what’s happening in these first moments and to feel confident in the decisions you make for your baby.
