Weighted sleep sacks are wearable blankets with added weight distributed evenly to promote better sleep. The added weight is intended to provide deep pressure stimulation (DPS), a therapy method that uses gentle pressure to relax the central nervous system. DPS can help calm babies and prepare them for sleep by releasing neurochemicals that regulate emotions, calmness, and relaxation. However, while some parents advocate for their use, experts, including the American Academy of Pediatrics (AAP), caution against them due to safety concerns. The AAP warns that placing weight on sleeping babies poses a potentially fatal risk, and there have been reported cases of infants dying while wearing weighted sleep sacks or swaddles.

What You'll Learn

They can help calm babies down and prepare them for sleep
Weighted sleep sacks are wearable blankets with an added gentle weight to promote better sleep. The weight is evenly distributed throughout the sleep sack so that babies can benefit from shoulder-to-toe deep pressure stimulation (DPS). DPS is a therapy method that uses gentle pressure to relax the central nervous system. This can be beneficial for everyone, but especially for young babies whose bodies are still learning to regulate their nervous systems.
Babies experience a multitude of milestones and learning opportunities as they grow. Their minds and bodies are constantly processing information to learn how to operate outside the womb. This can dysregulate their nervous systems, significantly impacting their sleep, digestive system, mood, and behaviour.
Weighted sleep sacks can help calm babies down and prepare them for sleep by releasing neurochemicals that help to regulate emotions, feel calm, and relax. Gentle deep-pressure stimulation sends cues to the body to release and produce dopamine and serotonin, which decrease the body's fight or flight responses and overactive nervous systems. They can also stimulate the areas of the brain responsible for melatonin production, the sleep chemical.
However, it is important to note that while some parents say that weighted sleep sacks calm their babies, experts warn that they can be dangerous. The American Academy of Pediatrics (AAP) has advised parents against using weighted sleep sacks, saying they "are not safe and not recommended". The AAP warns that placing weight on babies while they sleep poses an alarming and potentially fatal risk, and could increase the risk of sudden infant death syndrome by making it harder for babies to arouse themselves in response to hazards. The Consumer Product Safety Commission (CPSC) has also updated its safe sleep guidelines to address weighted sleep sacks, listing them in the "don't" category.

They can help babies sleep for longer
While many parents are curious about when to use sleep sacks, it is important to note that the American Academy of Pediatrics (AAP) has advised against the use of weighted sleep sacks for infants. The AAP warns that placing weight on babies while they sleep poses an alarming and potentially fatal risk. Federal regulators have not warned of any deaths, but records from the Consumer Product Safety Commission (CPSC) list at least one infant death involving a weighted sleep sack, although it is unclear whether the sack played a role. The CPSC has updated its safe sleep guidelines to address weighted sleep sacks, listing them in the "don't" category.
Despite the concerns raised by the AAP and CPSC, some companies that produce weighted sleep sacks, such as Dreamland Baby and Nested Bean, maintain that their products are safe when used as directed. They compare the sensation of using a weighted sleep sack to a parent's hand gently resting on an infant's chest or the feeling of "being held and hugged." These companies hope that further research will lead the AAP to reverse its recommendations.
Weighted sleep sacks are designed to provide deep pressure stimulation (DPS), a therapy method that uses gentle weighted touch to relax the central nervous system. DPS can help calm babies, regulate their emotions, and prepare them for sleep by releasing neurochemicals like dopamine, serotonin, and melatonin. This can lead to longer and better sleep for babies.
While weighted sleep sacks may have potential benefits, it is crucial to prioritize the safety of infants. Parents should carefully consider the risks and follow the recommendations of trusted medical organizations like the AAP and CPSC. There are alternative safe sleep-promoting products for babies, such as non-weighted swaddle blankets, non-weighted wearable blankets, and pacifiers, which can help newborns sleep longer without the potential risks associated with weighted sleep sacks.

They can improve a baby's mood
While many parents say that weighted sleep sacks calm their babies, experts warn that they can be dangerous. The American Academy of Pediatrics (AAP) has advised parents against using weighted sleep sacks, weighted swaddles, weighted clothing, or weighted objects on or near babies. The AAP warns that placing weight on babies while they sleep poses an alarming and potentially fatal risk.
However, some companies that make weighted sleep sacks, such as Nested Bean and Dreamland Baby, maintain that their products are safe. They liken their products to the sensation of "being held and hugged" or a parent's hand resting gently on an infant's chest.
Weighted sleep sacks can improve a baby's mood by providing deep pressure stimulation (DPS), a therapy method that utilizes a gently weighted touch to relax the central nervous system. DPS can help calm a baby's nervous system and prepare them for sleep by releasing neurochemicals that help to regulate emotions, feel calm, and relax. Gentle deep-pressure stimulation sends cues to the body to release and produce dopamine and serotonin, which decrease the body's fight or flight responses and overactive nervous systems. These "happy chemicals" can also stimulate areas of the brain responsible for melatonin production, which can help a baby sleep longer and better.
While weighted sleep sacks may have potential benefits for a baby's mood, it is important to carefully consider the potential risks associated with their use.

They can be dangerous and increase the risk of sudden infant death syndrome
Weighted sleep sacks are wearable blankets with zippers, snaps, or velcro to help the garment stay on the baby even as they move around during sleep. They are marketed as a way to reduce anxiety and have a soothing effect on the baby. However, many experts, including those at the American Academy of Pediatrics (AAP), caution against their use.
The AAP has warned that weighted sleep sacks could increase the risk of sudden infant death syndrome (SIDS) by making it harder for babies to arouse themselves in response to hazards such as a lack of oxygen. Dr. Michael Goodstein, a neonatologist and member of the AAP's task force on SIDS, expressed concern about the potential compression of infants' chests and the resulting impact on their breathing. The flexible nature of infants' rib cages means that added weight could restrict their chest movement and affect their respiratory function.
Research has also indicated the potential for oxygen saturation levels to decline to unsafe levels during longer sleeping periods. Dr. Rachel Moon, the chair of the AAP's task force on SIDS, highlighted the risk of infants experiencing fatigue, which could further compromise their ability to breathe. The AAP has urged regulatory bodies to be more stringent about the sale of weighted infant products to prevent tragic incidents.
Indeed, there have been reported cases of infants dying while wearing weighted sleep sacks or swaddle blankets. While the role of these products in the deaths is not always clear, the potential dangers they pose cannot be overlooked.
While companies that produce weighted sleep sacks, such as Nested Bean and Dreamland Baby, maintain the safety of their products, it is essential for parents and caregivers to carefully consider the potential risks. The AAP and other medical professionals recommend alternative methods to promote safe sleep in infants, such as swaddling with non-weighted blankets, using pacifiers, rocking, and shushing techniques.

There are safer alternatives to help babies sleep
Weighted sleep sacks are popular among parents due to their purported ability to soothe and calm babies, promoting better sleep. However, many experts, including those at the American Academy of Pediatrics (AAP) and the United States Consumer Product Safety Commission (CPSC), advise against using them due to safety concerns. The added weight could restrict a baby's movement, impair breathing, and increase the risk of suffocation. Additionally, the deep sleep promoted by these products might make it challenging for babies to wake up, raising the risk of Sudden Infant Death Syndrome (SIDS).
So, what are some safer alternatives to help your baby sleep? Firstly, you can create a bedtime routine with activities like reading, bathtime, songs, and baby massage. Consistency in the routine can help babies calm down and know what to expect. Secondly, you can use non-weighted sleep sacks or wearable blankets that provide a cozy sleeping environment without the risks associated with added weight. The Woolino sleep sack, for instance, is thicker than other sleep sacks, giving it natural weight without the safety concerns of weighted products. The Kyte Baby Sleep Bag is another popular option that helps babies fall and stay asleep, regulates temperature, and makes diaper changes easier.
For newborns, a tightly wrapped, non-weighted swaddle blanket can be beneficial. Dr. Katz recommends losing the swaddle once the baby starts to roll over, usually around three months, and transitioning to a sleeveless, non-weighted sleep sack to allow free movement of the baby's arms. Pacifiers are another safe option endorsed by Dr. Katz, as they have been shown to reduce the risk of SIDS when used correctly. Finally, contact naps can be a safe and effective way to help your baby sleep. You can hold your baby and watch a show or listen to music, treasuring the cuddles while also getting some rest.
