Breastfeeding has long been touted as one of the most effective ways to promote infant health and development. From providing essential nutrients to boosting the immune system, the benefits of breastfeeding are numerous and well-documented. However, one of the most significant advantages of breastfeeding is its ability to decrease the risk of Sudden Infant Death Syndrome (SIDS). But why does breastfeeding have this profound impact on SIDS risk? In this article, we’ll delve into the latest research and explore the reasons behind this remarkable correlation.
Understanding SIDS
Before we dive into the relationship between breastfeeding and SIDS, it’s essential to understand what SIDS is and how it affects infants. SIDS, also known as crib death or cot death, is the sudden and unexplained death of an infant under one year of age. According to the American Academy of Pediatrics (AAP), SIDS is the leading cause of death among infants between one month and one year old, accounting for approximately 3,500 deaths per year in the United States alone.
Despite extensive research, the exact causes of SIDS remain unclear. However, studies have identified several risk factors that increase an infant’s likelihood of experiencing SIDS. These include:
- Premature birth
- Low birth weight
- Exposure to tobacco smoke
- Sleeping on the stomach or side
- Overheating
- Bed-sharing
The Breastfeeding-SIDS Connection
Numerous studies have demonstrated a significant correlation between breastfeeding and a reduced risk of SIDS. A 2019 meta-analysis published in the journal Pediatrics found that breastfeeding was associated with a 50% lower risk of SIDS compared to formula-feeding. Another study published in the Journal of Pediatrics in 2018 found that exclusive breastfeeding for at least two months reduced the risk of SIDS by 73%.
But what is it about breastfeeding that makes it so effective in reducing SIDS risk? Researchers have identified several key factors that contribute to this correlation.
Improved Sleep Patterns
Breastfeeding has been shown to promote healthier sleep patterns in infants. Breastfed babies tend to have more frequent, shorter sleep periods, which can help reduce the risk of SIDS. This is because shorter sleep periods allow for more opportunities for infants to wake up and reposition themselves, reducing the likelihood of becoming trapped in a compromised position.
In contrast, formula-fed babies tend to have longer, more consolidated sleep periods, which can increase the risk of SIDS. A study published in the Journal of Sleep Research found that formula-fed babies were more likely to experience deep sleep, which can make it more difficult for them to wake up and respond to their environment.
Increased Arousal
Breastfeeding has also been shown to increase infant arousal, which can help reduce the risk of SIDS. Arousal refers to an infant’s ability to wake up and respond to their environment. Breastfed babies tend to have higher levels of arousal, which can help them respond to potential threats, such as becoming trapped in a compromised position.
A study published in the Journal of Perinatology found that breastfed babies had higher levels of arousal during sleep compared to formula-fed babies. This increased arousal can help breastfed babies wake up and reposition themselves, reducing the risk of SIDS.
Reduced Inflammation
Breast milk contains anti-inflammatory properties that can help reduce inflammation in the infant’s body. Chronic inflammation has been linked to an increased risk of SIDS, so the anti-inflammatory effects of breast milk may help mitigate this risk.
A study published in the Journal of Nutrition found that breast milk contained high levels of anti-inflammatory cytokines, which can help reduce inflammation in the infant’s body. This reduced inflammation can help reduce the risk of SIDS.
Improved Immune Function
Breast milk contains immunoglobulins, which are proteins that help fight infection. These immunoglobulins can help protect the infant from infections that can increase the risk of SIDS.
A study published in the Journal of Infectious Diseases found that breast milk contained high levels of immunoglobulins, which can help protect the infant from infections. This improved immune function can help reduce the risk of SIDS.
Other Factors At Play
While the factors mentioned above are likely to contribute to the reduced risk of SIDS associated with breastfeeding, other factors may also be at play. For example:
Maternal-Infant Interaction
Breastfeeding promotes maternal-infant interaction, which can help reduce the risk of SIDS. Skin-to-skin contact and frequent feeding can help promote a strong bond between mother and baby, which can reduce the risk of SIDS.
Bed-Sharing
Breastfeeding mothers are more likely to bed-share with their babies, which can reduce the risk of SIDS. Bed-sharing allows for closer proximity between mother and baby, which can help promote a safer sleep environment.
Conclusion
The correlation between breastfeeding and a reduced risk of SIDS is clear. By promoting healthier sleep patterns, increasing arousal, reducing inflammation, and improving immune function, breastfeeding can help mitigate the risk of SIDS. While other factors, such as maternal-infant interaction and bed-sharing, may also contribute to this correlation, the evidence is clear: breastfeeding is a powerful tool in reducing the risk of SIDS.
As healthcare providers and policymakers, it’s essential that we promote breastfeeding as a key strategy for reducing the risk of SIDS. By supporting breastfeeding mothers and providing them with the resources they need to succeed, we can help reduce the incidence of SIDS and promote healthier outcomes for infants.

By understanding the complex relationship between breastfeeding and SIDS, we can work towards creating a safer sleep environment for all infants.
What Is SIDS And How Is It Related To Breastfeeding?
Sudden Infant Death Syndrome (SIDS) is the sudden, unexplained death of a baby younger than one year of age that doesn’t have a known cause even after a complete investigation, including an autopsy. Research has shown that breastfeeding can significantly decrease the risk of SIDS. Studies have consistently found that breastfed babies are less likely to die from SIDS compared to formula-fed babies.
The exact mechanism of how breastfeeding reduces SIDS risk is not fully understood, but several theories have been proposed. One theory is that breastfeeding promotes a more stable sleep pattern in babies, which may reduce the risk of SIDS. Another theory is that breast milk contains antibodies and other immune factors that help protect babies from infections, which may also reduce the risk of SIDS.
How Much Does Breastfeeding Reduce The Risk Of SIDS?
Breastfeeding has been shown to significantly reduce the risk of SIDS. According to the American Academy of Pediatrics (AAP), breastfeeding can reduce the risk of SIDS by 50-70%. This means that babies who are breastfed are half to two-thirds less likely to die from SIDS compared to formula-fed babies.
The AAP recommends exclusive breastfeeding for the first six months of life, and continued breastfeeding as complementary foods are introduced, for at least 12 months. By following these recommendations, mothers can significantly reduce their baby’s risk of SIDS.
Is The Reduced Risk Of SIDS Due To Breastfeeding Itself Or Other Factors?
While breastfeeding itself is thought to be the primary factor in reducing SIDS risk, other factors may also play a role. For example, mothers who breastfeed may be more likely to follow other safe sleep practices, such as placing their baby on their back to sleep and avoiding bed-sharing.
However, studies have controlled for these other factors and still found a significant reduction in SIDS risk associated with breastfeeding. This suggests that breastfeeding itself has a protective effect against SIDS, although the exact mechanisms are not yet fully understood.
Does The Duration Of Breastfeeding Affect The Reduced Risk Of SIDS?
Yes, the duration of breastfeeding does appear to affect the reduced risk of SIDS. Studies have found that the longer a baby is breastfed, the lower their risk of SIDS. Exclusive breastfeeding for at least two months has been shown to have a significant protective effect against SIDS.
However, even partial breastfeeding or breastfeeding for a shorter duration may still offer some protection against SIDS. The AAP recommends exclusive breastfeeding for the first six months of life, and continued breastfeeding as complementary foods are introduced, for at least 12 months.
Can Breastfeeding Reduce The Risk Of SIDS In Premature Babies?
Yes, breastfeeding can reduce the risk of SIDS in premature babies. Premature babies are at higher risk of SIDS due to their immature development and increased risk of respiratory problems. However, studies have found that breastfeeding can significantly reduce this risk.
In fact, the AAP recommends that premature babies be breastfed as soon as possible after birth, as this can help reduce their risk of SIDS and other complications. Mothers of premature babies may need to express their milk and feed it to their baby through a tube or bottle until the baby is able to breastfeed directly.
Can Breastfeeding Reduce The Risk Of SIDS In Babies With A Family History Of SIDS?
Yes, breastfeeding can reduce the risk of SIDS in babies with a family history of SIDS. While a family history of SIDS does increase a baby’s risk, breastfeeding can still offer significant protection.
In fact, the AAP recommends that mothers with a family history of SIDS breastfeed their babies exclusively for at least six months, and continue breastfeeding as complementary foods are introduced, for at least 12 months. This can help reduce the baby’s risk of SIDS, even if there is a family history of the condition.
What Other Ways Can Mothers Reduce Their Baby’s Risk Of SIDS?
In addition to breastfeeding, there are several other ways that mothers can reduce their baby’s risk of SIDS. These include placing the baby on their back to sleep, using a firm sleep surface, keeping the sleep environment cool, and avoiding bed-sharing and soft bedding.
Mothers can also reduce their baby’s risk of SIDS by avoiding exposure to tobacco smoke and other pollutants, and by getting regular prenatal care during pregnancy. By following these recommendations, mothers can significantly reduce their baby’s risk of SIDS.
