When can a baby sleep with a blanket? Experts advise waiting until at least 12 months old due to suffocation and SIDS risks. This article covers these risks and safer alternatives.
Key Takeaways
Blankets should not be used in an infant’s crib until at least 12 months old to reduce risks of SIDS and suffocation.
Safe alternatives to blankets, such as sleep sacks and appropriate layering, can keep babies warm without the associated dangers of loose bedding.
Room sharing is advised over bed sharing to reduce the risk of SIDS, providing safety benefits while allowing easy monitoring of the infant.
Understanding the Risks of Blankets for Babies

While blankets might appear to be a comforting option for warmth, they come with significant risks. Their use in a baby’s crib elevates the chances of SIDS and accidental suffocation. Nearly 70% of sleep-related suffocation deaths in infants are attributed to loose blankets. The dangers also include entrapment and strangulation, underscoring the importance of adhering to safe sleep guidelines.
Blankets present serious dangers. Loose blankets can cover a baby’s mouth and nose, restricting breathing and causing rebreathing of stale air. This can lower oxygen levels and increase carbon dioxide levels, posing severe health risks for the infant. Recognizing these risks is crucial for creating a safe sleep environment for your baby.
How Blankets Increase SIDS Risk
Sudden Infant Death Syndrome (SIDS) is a major concern for new parents, and blankets can considerably elevate this risk. Soft bedding items like blankets, pillows, and stuffed animals can obstruct a baby’s airway, leading to accidental suffocation. Although these items are intended to provide comfort, they can be extremely hazardous in a crib setting.
Loose blankets pose a suffocation risk by potentially covering a baby’s mouth and nose, leading to infant suffocation. This can restrict breathing and lead to rebreathing, where the baby inhales the same breath repeatedly, reducing oxygen levels and increasing carbon dioxide levels. This situation can quickly become life-threatening.
Keeping the crib empty is essential for a safe sleep environment.
When Is It Safe for Babies to Sleep With a Blanket?

Many parents are curious about when it is safe to introduce blankets into their baby’s sleep routine. The American Academy of Pediatrics (AAP) advises waiting until a baby is at least 12 months old before allowing them to sleep with a blanket. This recommendation is based on developmental milestones, such as the ability to roll over and move objects away from their face, typically reached around this age.
Even after the first birthday, caution remains important. Some experts suggest waiting until 18 months to further minimize risks. At this age, babies have improved motor skills and are less likely to become entangled in a blanket, reducing suffocation risks.
Consulting a healthcare provider can offer personalized guidance based on your baby’s development.
Age Recommendations for Blanket Use
The AAP firmly advises against allowing babies to sleep with blankets or any other soft objects in their cribs until they are at least 12 months old. This age guideline aims to reduce the risk of suffocation and ensure a safe sleep environment. Some parents may worry about keeping their baby warm without a blanket, but safer alternatives are available.
After the first birthday, some experts recommend waiting until 18 months to introduce blankets. This extended period allows babies to develop more advanced motor skills, reducing the likelihood of entanglement in a blanket. Consult your pediatrician for personalized advice on what’s best for your baby.
Alternatives to Blankets for Keeping Baby Warm

Keeping your baby warm without a blanket is both possible and safer. A sleep sack is one of the best alternatives to traditional blankets. Sleep sacks keep babies warm while significantly reducing risks associated with loose bedding. These wearable blankets offer warmth without the dangers of suffocation and overheating.

Using a baby’s sleep sack ensures your sleeping baby safe stays warm and safe throughout the night, helping them to fall asleep comfortably. The design of sleep sacks eliminates the need for loose blankets, making them a practical choice for safety-conscious parents. Incorporating a swaddle or sleep sack can enhance baby sleep quality and promote when the sleeping baby sleeps.
Dressing Your Baby Appropriately
Dressing your baby in layers is another effective way to keep them warm without blankets. Dress your baby in one more layer than you would wear yourself to keep them warm. Lightweight swaddles or wearable blankets can add warmth without the risks of loose bedding.
To check if your baby is warm enough, feel the nape of their neck. If it’s warm but not sweaty, your baby is likely dressed appropriately. Avoid synthetic fabrics like fleece, which can cause overheating. Proper layering and fabric choice are essential for maintaining your baby’s comfort and safety.
Swaddling: A Safe Option Until Baby Can Use a Blanket
Swaddling is a time-tested method to keep your baby warm and secure until they can use a blanket. When done correctly, swaddling can reduce the risk of SIDS and comfort your baby. A swaddle blanket, specifically designed for this purpose, is a great alternative to traditional blankets.
The AAP advises against using weighted swaddles or sleep sacks due to potential risks. Instead, choose regular swaddle blankets or sleep sacks designed to be safe and effective. Knowing how to swaddle safely is crucial for maintaining a safe sleep environment for your baby. AAP policy explained highlights the importance of these guidelines.
How to Swaddle Safely
Safe swaddling involves using light cotton or muslin blankets about 47 inches by 47 inches in size. The swaddle should be snug around your baby’s arms but loose around the hips to allow proper hip development and avoid restricting breathing. Alternatives like Happiest Baby’s Sleepea can simplify the process while ensuring a safe swaddle.
Avoid overheating by ensuring the baby’s head isn’t covered and regularly monitoring for excessive warmth. Layering blankets over a swaddled baby increases suffocation risks and should be avoided. Following these guidelines helps keep your baby safe and comfortable.
Transitioning From Swaddling
Stop swaddling as soon as your baby can roll over to ensure their safety. Babies can typically remain swaddled until about 6 months old, especially if using a product like the SNOO. Once your baby starts rolling over, transitioning to sleep sacks and other safe sleep options is crucial for safety.
Make this transition smoother by gradually reducing swaddling time and introducing sleep sacks, which offer similar security without the risks. A safe transition helps maintain a secure sleep environment for your baby.
Creating a Safe Sleep Environment

A safe sleep environment is vital for reducing the risks of SIDS and other sleep-related hazards. The recommended sleeping position for babies is on their backs, significantly reducing the risk of SIDS. An empty crib or bassinet with only a fitted sheet is ideal for a safe sleep setup.
Room sharing can lower the risk of SIDS while allowing for easy monitoring and feeding without bed-sharing risks. Maintaining a moderate temperature and using lightweight bedding can further reduce overheating and suffocation risks.
Keep the Crib Free of Loose Items
To ensure a safe sleeping environment, follow these guidelines:
Keep the crib free of loose items like blankets, pillows, and stuffed animals.
Soft bedding, including blankets and pillows, should be kept out of the baby’s sleep area to prevent suffocation.
A firm and flat crib mattress is essential for adequate support and reducing suffocation risks.
Selecting a CPSC-approved crib or bassinet ensures safety standards are met, providing the safest sleep environment for the best sleep. Keeping the crib empty and following these guidelines significantly reduces sleep-related hazards.
