Understanding Sudden Infant Death Syndrome (SIDS): Awareness and Prevention

October is recognized as Sudden Infant Death Syndrome (SIDS) Awareness Month. Each year, around 3,400 infants in the United States die suddenly and unexpectedly, with SIDS accounting for a significant portion of these deaths. By increasing our understanding of SIDS’ risk factors, we can better prevent SIDS, and support affected families.

What is SIDS?

Sudden infant death syndrome (SIDS) is defined as the sudden and unexplained death of a baby younger than 1 year old, usually occurring during sleep. Commonly referred to as “crib death,” SIDS is one of the leading causes of infant mortality between 1 month and 1 year of age, particularly between 2 and 4 months old. Despite extensive research, the exact cause of SIDS remains unknown. However, certain factors have been identified that may increase the risk.

Identifying Risk Factors

SIDS is associated with several risk factors that can be divided into maternal, infant, and environmental categories:

• Maternal Factors: These include being a young mother, smoking during pregnancy, inadequate prenatal care, not breastfeeding, and using alcohol or illegal drugs.
• Infant Factors: Babies born prematurely or with low birth weight are at a higher risk. Additionally, sleeping positions and environmental exposures play a significant role. Infants who sleep on their bellies, are exposed to secondhand smoke, sleep on soft surfaces, or co-sleep are at increased risk.

Preventative Measures

Implementing safe sleep practices can greatly reduce the risk of SIDS:

• Breastfeeding and Prenatal Care: Receiving regular prenatal care can lower the risk of SIDS. Avoid smoking during pregnancy. Ensure your baby receives all recommended vaccinations. Breastfeed for at least 6 months. For breastfeeding support, check out our breastfeeding support page. Learn more about the importance of prenatal care in our preconception and prenatal care section.
• Safe Sleep Environment: Keep your baby’s sleep area free from soft toys, and ensure the room is at a comfortable temperature. Avoid over bundling your baby and ensure their sleep environment is free from hazards like cords or curtains. Always place your baby on their back for sleep and naps. Use a firm, flat mattress with a fitted sheet in the crib, and avoid soft bedding such as pillows, blankets, or bumper pads. Don’t use sitting devices like car seats or swings for regular sleep. Don’t bed-share, especially if alcohol or drug use is involved. Room sharing without bed-sharing is recommended for at least the first 6 months.

• Other Preventative Actions: Incorporate tummy time when your baby is awake to help strengthen muscles. Offering a pacifier during sleep time can be beneficial. Additionally, take your baby for regular checkups and ensure your baby receives all their vaccinations.

Moving Forward

SIDS Awareness Month provides an important opportunity to educate and inform individuals about this devastating condition. By understanding the risk factors and implementing preventative measures, we can help reduce the incidence of SIDS, and support affected families.
