Baby Safety Basics: Understanding SIDS & SUID
As a new parent, there’s so much to think about when it comes to caring for your baby, and one of the most important things you can do is ensure your little one is safe while they sleep.
Sudden Infant Death Syndrome (SIDS) and Sudden Unexpected Infant Death (SUID) are two terms that you may have heard, and both refer to tragic, but preventable, sleep-related deaths in infants. While these topics can be difficult to think about, understanding the risks and knowing how to create a safe sleep environment for your baby is one of the most crucial steps you can take as a parent.
Here’s what every parent needs to know about SIDS and SUID, and how to reduce the risks to help keep your baby safe.
What is SIDS?
SIDS stands for Sudden Infant Death Syndrome and refers to the unexpected and unexplained death of an infant, typically while they’re sleeping. SIDS usually affects babies under one year old, with the majority of deaths occurring between the ages of 1 month and 4 months. Despite extensive research, the exact cause of SIDS remains unknown, but experts believe it may occur due to a combination of factors such as an immature brainstem, sleep environment, and genetics.
What is SUID?
SUID stands for Sudden Unexpected Infant Death, a broader term that encompasses any infant death that occurs suddenly and unexpectedly, including SIDS, accidental suffocation, or other sleep-related causes. While SIDS falls under the SUID umbrella, SUID can also include deaths from unsafe sleep environments such as suffocation from soft bedding or a baby being trapped in an unsafe position.
It’s important to note that SIDS is not caused by anything a parent does or doesn’t do. However, certain sleep practices can increase the risk of SIDS or SUID, which is why it’s essential for parents to be informed and take steps to reduce these risks.

6 Risk Factors to Know
While we don’t yet fully understand why SIDS and SUID happen, there are several factors that can increase the risk. Some of these factors can’t be controlled, such as a baby’s age or their genetic predisposition, but there are key steps parents can take to reduce the risks.
1. Sleep Position
- Back Sleeping: One of the most important ways to reduce the risk of SIDS is by always placing your baby on their back to sleep. Babies who are placed on their stomachs or sides to sleep are at a much higher risk for SIDS. The back position is the safest, and studies have shown that placing babies on their backs reduces the risk of SIDS.
2. Safe Sleep Environment
- Firm Mattress: Always place your baby on a firm mattress in a safety-approved crib, bassinet, or play yard. Soft surfaces such as pillows, blankets, and soft mattresses increase the risk of suffocation.
- No Soft Bedding: Keep the crib free of pillows, blankets, bumper pads, and stuffed animals. These can pose a suffocation hazard, especially if they get too close to your baby’s face during sleep.
- Proper Clothing: Dress your baby in a wearable blanket or sleep sack instead of loose blankets to prevent overheating and reduce suffocation risks.
3. Avoid Overheating
- Babies who become overheated during sleep are at higher risk for SIDS. Make sure your baby’s room is a comfortable temperature (around 68-72°F or 20-22°C) and avoid overdressing them. Use a light sleep sack or onesie, and never cover your baby’s head with blankets.
4. Room Sharing
- The American Academy of Pediatrics (AAP) recommends room sharing—having your baby sleep in the same room as you, but on their own separate sleep surface, such as a crib or bassinet—at least for the first 6 months. Room sharing has been shown to reduce the risk of SIDS by as much as 50%, while still allowing you to be close enough to respond to your baby’s needs during the night.
5. Avoid Smoking and Secondhand Smoke
- Babies who are exposed to cigarette smoke, either during pregnancy or after birth, are at a higher risk for SIDS and SUID. Make sure your baby’s sleep environment is smoke-free, and if you or anyone else in the household smokes, do so away from the baby, and ideally, outside of the home.
6. Breastfeeding
Breastfeeding has been shown to reduce the risk of SIDS. If possible, try to breastfeed your baby, as it offers numerous health benefits for both you and your baby, including providing immune support and helping to regulate your baby’s sleep patterns.
Additional Guidelines to Help Keep Your Baby Safe
- Tummy Time: When your baby is awake and supervised, give them plenty of tummy time. This helps strengthen their muscles and develop motor skills, which can reduce the risk of flat spots on their head and promote healthy development.
- Vaccinations: Keeping your baby up-to-date with their vaccinations has been shown to lower the risk of SIDS. Make sure you follow your pediatrician’s recommended vaccination schedule.
- Avoid Bedsharing: While room sharing is recommended, bedsharing (having your baby sleep in your bed) is not. Bedsharing increases the risk of suffocation, falls, and overheating. Your baby should sleep in their own crib or bassinet, even if they share your room.
The Bottom Line: Creating a Safe Sleep Environment
While the exact causes of SIDS and SUID remain unclear, we do know that safe sleep practices can reduce the risks. By following the guidelines provided by experts and taking steps to create a safe, comfortable sleep space for your baby, you can help ensure that your baby has the best chance for a safe sleep.
As a mom, your instinct is to protect and nurture your baby, and by being aware of the risks and safety measures related to SIDS and SUID, you’re already making a huge difference. Taking these small, proactive steps can help provide peace of mind and give your baby the safe and restful sleep they need to grow and thrive.
Final Thoughts
SIDS and SUID can be unsettling topics for new parents, but they’re also important to understand. As you prepare for your baby’s arrival, remember that safe sleep practices are your best line of defense in reducing the risks. Always consult your pediatrician if you have any questions or concerns, and know that by creating a safe sleep environment, you are doing everything you can to help keep your baby safe and healthy.
