Significance of Skin-to-Skin Contact and Delayed Cord Clamping at Birth and the Science
The moments immediately following birth are crucial, not only for emotional bonding but also for the physiological well-being of the newborn. One of the most beneficial practices is allowing the newborn to remain on their mother’s chest for at least an hour after birth. This instinctive closeness is supported by nature itself: the umbilical cord is 50–60 centimeters long, perfectly designed to keep the baby within reach of the mother’s breast, facilitating this essential contact and connection.
Immediate Contact: More Than Just Bonding
When a baby is placed on the mother’s chest, a powerful hormonal exchange occurs, releasing oxytocin in both the mother and child. This "love hormone" helps regulate the baby's heartbeat, breathing, and temperature, promoting stability in the newborn’s first moments outside the womb. This skin-to-skin contact also triggers the infant’s innate ability to locate the breast and begin breastfeeding, which has been shown to improve breastfeeding success rates and encourage the milk production process.
Beyond emotional bonding, this first hour of skin-to-skin contact helps initiate breastfeeding, a significant factor in long-term health. Early breastfeeding within this "golden hour" aids in developing the baby’s immune system, enhances mother-child bonding, and sets a positive foundation for the newborn's health.
Delayed Cord Clamping: Supporting Baby’s Blood Volume
Another vital component of birth care is delayed cord clamping, which aligns with the body’s natural processes. At the time of birth, around 25% of the baby’s blood volume still resides in the placenta. By delaying the cutting of the umbilical cord for at least 25 minutes, this blood gradually transfers to the baby, providing additional iron and oxygen-carrying red blood cells.
Allowing this transfer of blood from the placenta to the newborn has been linked to numerous health benefits. It supports an increased blood volume, which lowers the risk of anemia in infancy, and ensures the newborn receives critical stem cells and immune cells that aid in the body’s healing and defense mechanisms. Studies show that babies who experience delayed cord clamping may enjoy improved developmental outcomes in early childhood.

An Evolution in Newborn Care
The movement toward prolonged skin-to-skin contact and delayed cord clamping marks a shift in birth practices. Hospitals worldwide increasingly encourage these methods, recognizing the profound impact they have on newborn health and maternal bonding.
Allowing newborns to stay close to their mothers immediately after birth and letting the cord provide its remaining blood is a practice backed by science and the natural design of birth. These two steps, though simple, have transformative health benefits that can shape a baby’s journey into life and support the mother-child bond from the very first moment.

Scientific Studies
There are numerous studies on this subject, with at least a few dozen focusing specifically on delayed cord clamping, and many more examining skin-to-skin contact and early bonding post-birth.
The Benefits of Delayed Umbilical Cord Clamping
When a newborn is delivered, keeping the umbilical cord intact for a period before clamping has shown significant health benefits. Immediate clamping, previously common in medical practice, is now contrasted with delayed cord clamping (DCC), which allows the transfer of vital blood from the placenta to the infant, particularly beneficial within the first few minutes after birth.
1. Increased Blood Volume and Reduced Risk of Anemia
At birth, roughly a quarter of a newborn’s blood remains in the placenta. By delaying clamping by just 25 to 60 seconds, studies show that infants receive additional blood volume, leading to higher hemoglobin levels, and increased iron reserves, which help reduce the risk of anemia in the first months of life. This benefit is particularly noted in full-term infants, who can safely wait for the transfusion from the placenta to complete without intervention

2. Support for Brain Development
Research supported by the National Institutes of Health highlights potential neurodevelopmental advantages associated with DCC. By increasing the iron load, which is crucial for brain development, delayed clamping has been correlated with improved myelination (the formation of protective sheaths around neurons) in areas of the brain responsible for motor skills, sensory processing, and visual-spatial capabilities. Infants who experienced DCC have shown stronger developmental outcomes at 4 to 12 months compared to those who had early clamping NICHD.

3. Reduced Need for Blood Transfusions in Preterm Infants
DCC has proven beneficial for preterm infants, reducing the likelihood of requiring blood transfusions for low blood volume or related complications. However, the timing and application of DCC for preterm infants may vary based on their stability at birth, as some infants may need immediate medical support
