Potential risk of asphyxiation
The use of weighted sleep sacks for babies has sparked concerns about potential asphyxiation risks, prompting warnings from doctors and the American Academy of Pediatrics (AAP). While some manufacturers claim their products are safe, the AAP advises against placing weighted sleep sacks or blankets near sleeping infants.
The primary concern is the risk of impaired arousal, where a baby may struggle to wake up promptly in distressing situations, such as a lack of oxygen. This impaired arousal could contribute to Sudden Infant Death Syndrome (SIDS) and increase the risk of sudden unexpected infant death. The AAP's recommendation aims to reduce these unexpected deaths by discouraging the use of weighted sleep products.
Additionally, the beads or pellets used to weigh down sleep sacks and swaddle blankets have raised concerns among experts. The presence of these small objects in the sleeping environment may pose a potential hazard if they become loose or accessible to the infant.
While there have been reports of infant deaths while using weighted sleep sacks, it is unclear if the sacks were the direct cause. The Consumer Product Safety Commission (CPSC) records indicate at least one death associated with a weighted sleep sack and another with a weighted swaddle blanket. However, the specific brands or types of swaddles were not always mentioned in the reports, making it challenging to determine the exact role of weighted sleep sacks in these incidents.
To ensure the safety of infants, it is crucial to follow the recommendations of reputable medical organizations and prioritize creating a safe sleeping environment. The AAP and CPSC provide guidelines for infant sleep safety, urging parents to avoid weighted sleep sacks and opt for non-weighted alternatives.

Doctor's advice against weighted sleep sacks
Weighted sleep sacks are sleepwear products designed to help babies sleep longer. They are wearable blankets with zippers, snaps, or velcro to help the garment stay on the baby even as they move during sleep. The weights are sewn within the garment to provide gentle pressure across a baby's body, mimicking the pressure of a parent's hand or body, which helps soothe and settle babies.
Despite their popularity, doctors advise against using weighted sleep sacks for babies. The American Academy of Pediatrics (AAP) has updated its sleep guidelines to include weighted sleep sacks in the \"don't\" category for infant sleep safety. The AAP's recommendations are based on concerns regarding impaired arousal, which is the inability of a baby to wake up quickly in a time of distress, increasing the risk of sudden unexpected infant death or SIDS.
Additionally, doctors are concerned about the beads or pellets used to weigh down these sleep sacks, which may pose a choking hazard if they spill out of the fabric. The Consumer Product Safety Commission (CPSC) has long banned the use of beads in pillows for this reason.
There have been reports of infant deaths associated with weighted sleep sacks, with at least two deaths specifically linked to the Nested Bean brand. While the sleep sacks were not indicated as the cause of death in these cases, the potential risk is a significant concern for doctors and parents alike.
Instead of weighted sleep sacks, doctors recommend creating a safe sleeping environment for infants by following the ABCs of safe sleep. They suggest using non-weighted swaddle blankets for newborns, transitioning to non-weighted sleep sacks once the baby starts to roll over, usually around three months.

Safe alternatives for better sleep
Weighted sleep sacks for babies have been linked to infant deaths, with the American Academy of Pediatrics (AAP) and Consumer Product Safety Commission (CPSC) warning against their use. The AAP and CPSC have urged regulatory bodies to be stricter about the sale of weighted infant products. Doctors advise against using weighted sleep sacks or weighted blankets for babies, as they can impair arousal and increase the risk of sudden unexpected infant death or SIDS.
For Babies
- Swaddle blankets: A tightly wrapped, non-weighted swaddle blanket is recommended for newborns. However, Dr Katz advises that once the baby starts to roll over (usually around 3 months), it's time to lose the swaddle.
- Non-weighted wearable blankets: After a baby has outgrown swaddling, parents can transition to a non-weighted sleep sack.
- Contact naps: Holding your baby while they nap can be a safe alternative. You can set up headphones and a tablet to watch something while your baby sleeps.
- Follow wake windows, settling methods, and gentle sleep training: These methods can help your baby get longer sleep without the use of weighted sacks.
For Adults
- Natural sleep aids: There are several natural sleep aids that can help improve your sleep. For example, drinking warm milk, chamomile tea, or tart cherry juice before bed might support a healthy sleep cycle.
- Melatonin supplements: Melatonin is a hormone that is naturally released in the brain a few hours before we feel sleepy. Taking melatonin supplements can help regulate your sleep cycle, especially if you are exposed to a lot of unnatural light after dark.
- Keep your room cool and dark: The ideal temperature for your room is between 65 and 72 degrees Fahrenheit. Additionally, avoid turning on the lights if you need to get up at night, as the light can interfere with your sleep.
- Exercise: Moderate aerobic exercise can increase the amount of slow-wave (deep) sleep you get. However, make sure to time your workouts, as aerobic exercise releases endorphins that can keep you awake.

Overheating and fabric considerations
While weighted sleep sacks are designed for newborns up to toddlers, there are concerns about their safety. The American Academy of Pediatrics (AAP) has warned that weighted sleep sacks and swaddles could be deadly and increase the risk of sudden infant death syndrome (SIDS). According to the AAP, the very thing weighted products claim to do—help a baby stay asleep—is a concern as it may contribute to SIDS by impairing arousal, or the inability of a baby to wake up quickly in response to distress.
Overheating is a valid concern when using any sleep product, including weighted sleep sacks, swaddles, blankets, or pajamas. To prevent overheating, it is important to dress your baby appropriately for the weather and consider the fabric of the sleep sack. Some materials, such as cotton and bamboo, are more breathable than others. For example, during warmer months, your baby can wear just a diaper under their weighted sleep sack, while during colder months, you can pair it with bamboo pajamas.
It is recommended to look for the Thermal Overall Grade (TOG) on sleep sacks or swaddles, which indicates the appropriate temperature for use. Additionally, sizing is crucial when it comes to weighted sleep sacks. It is important to follow the product recommendations and choose the right size based on your baby's weight and length to ensure safety.
While some popular manufacturers of weighted sleep sacks, such as Dreamland Baby and Nested Bean, maintain that their products are safe, there have been reports of infant deaths linked to their use. However, it is unclear whether the weighted sleep sacks were a direct factor in these deaths. The Consumer Product Safety Commission (CPSC) has not issued any warnings specifically about weighted sleep sacks, but it has included them in a list of "don'ts" for infant sleep safety.
The AAP and CPSC recommend creating a safe sleeping environment for babies by keeping the crib clear of any items that could cause harm, such as bumpers, loose bedding, toys, and extra blankets. Instead, they suggest following the ABCs of safe sleep, which includes placing infants on their backs on a firm mattress with a fitted sheet. Non-weighted swaddle blankets and wearable blankets are considered safe alternatives to promote sleep in babies when used correctly.

Weighted sleep sacks for toddlers
Weighted sleep sacks are marketed as a solution for sleep-deprived parents, claiming to provide a soothing effect on infants and help them sleep better. However, the use of these products, particularly on toddlers, has sparked concerns and debates about their safety.
Potential Risks
The American Academy of Pediatrics (AAP) and a growing number of doctors and safe sleep advocates warn against the use of weighted sleep sacks for babies and toddlers. They assert that weighted sleepwear could pose a risk to infants, and the very thing these products claim to do—help a baby stay asleep—is a significant concern. According to the AAP, impaired arousal, or the inability of a baby to wake up quickly in a time of distress, may contribute to the risk of Sudden Infant Death Syndrome (SIDS). Additionally, the beads or pellets used to weigh down these sleep sacks have raised concerns among experts.
The Consumer Product Safety Commission (CPSC) has also addressed weighted sleep sacks in its safe sleep guidelines, listing them as a "don't" for infant sleep safety. There have been reports of infant deaths associated with the use of weighted sleep sacks and swaddle blankets, although the direct causation is unclear. However, the risk of impaired breathing due to pressure on the chest and abdomen, as well as the potential for restricted movement, cannot be ignored.
Manufacturer's Perspective
Manufacturers of weighted sleep sacks, such as Nested Bean and Dreamland Baby, defend the safety of their products. They claim to have conducted safety studies and assert that their products use a safe amount of weight. Nested Bean's weighted sleep sacks, for example, are designed with gently weighted Cuddle Pad™ technology, adjustable snaps, and a two-way zipper for ease of use. The company also provides guidelines recommending appropriate weighted products based on the baby's weight and does not suggest weighted sleepwear for infants under 6.5 pounds.
Alternatives and Recommendations
While weighted sleep sacks are controversial, there are alternative sleep-promoting products that doctors consider safe for toddlers when used correctly. These include non-weighted swaddle blankets for newborns and non-weighted wearable blankets for older babies who can no longer be swaddled safely. Dr. Rachel Moon, a pediatrician and chair of the AAP's task force on SIDS, recommends various alternatives to promote infant sleep, such as swaddling, pacifiers, rocking, and shushing.
In conclusion, while weighted sleep sacks for toddlers may be appealing to exhausted parents, the potential risks outlined by medical professionals and advocates cannot be overlooked. It is essential to prioritize the safety of infants, even if it means enduring some sleep deprivation. Following the recommendations and guidelines provided by organizations like the AAP and CPSC can help ensure a safer sleeping environment for toddlers.
