Sleep sacks are wearable blankets designed to keep babies warm and safe while sleeping. They are a popular accessory for parents and caregivers, as they reduce the risk of sudden infant death syndrome (SIDS) and provide a feeling of security for the baby. Sleep sacks are especially useful during the transition period between swaddling and giving the baby a blanket, as they allow babies to move their arms freely while keeping their legs covered. They are generally considered safe and can be used from the day a baby is born until they grow out of them.

What You'll Learn
Sleep sacks are a safer alternative to loose blankets
Sleep sacks, also known as wearable blankets, provide an extra layer of warmth without restricting a baby's arms. They form a pouch around the legs, allowing freedom of movement and making it harder for toddlers to climb out of their cribs. Sleep sacks also help maintain the correct body temperature, reducing the risk of overheating, which is another contributing factor to SIDS.
Sleep sacks are especially useful during the transition period when babies start rolling over and are no longer swaddled. They provide a feeling of security and can be used as a cue for sleep, making bedtime easier. Additionally, sleep sacks protect babies' legs from getting stuck between crib rails, reducing crib-related injuries.
It is recommended to use sleep sacks until at least 12 months of age, but they can be used beyond that if your child is comfortable and they still fit well.

They can be used from birth
Sleep sacks are wearable blankets that provide warmth to sleeping children without restricting their arm movement. They can be used from birth to toddlerhood and beyond, depending on the child's preference and size.
Sleep sacks are a safe alternative to loose blankets, which are not recommended for babies under 12 months old. They can be used from day one, although many parents opt to use swaddles for newborns until they show signs of rolling over (typically around 2-4 months of age). Sleep sacks are ideal for the transition period between swaddling and giving a baby a blanket.
Sleep sacks provide a feeling of security, similar to when the baby was in the womb. They can also be used for swaddling, which is a great way to soothe and calm a fussy baby and prevent the startle reflex, which can cause them to wake up. Sleep sacks help babies maintain the correct body temperature without becoming overheated, which is an important factor in reducing the risk of SIDS.
It's important to choose the right size sleep sack for your baby, as one that is too small could lead to suffocation, while an oversized sleep sack could lead to strangulation. Most sleep sacks have zippers or snap buttons for easy diaper changes, and it's recommended to dress your baby in a onesie or pajamas underneath.

They are available in different fabrics and sizes
Sleep sacks are available in a variety of fabrics and sizes to suit different needs and preferences. They are typically made from lightweight and breathable materials, such as cotton or Merino wool, to ensure that babies maintain a comfortable body temperature while sleeping. Merino wool, for instance, is a popular choice due to its ability to regulate body heat, keeping toddlers comfortable regardless of whether they are too hot or cold.
Sleep sacks come in different sizes, ranging from preemie to toddler sizes. The sizing is usually based on age, height, and weight, with some brands offering a size chart to help parents choose the right fit for their little ones. It is crucial to select the appropriate size to prevent the risk of suffocation or strangulation, which are contributing factors to Sudden Infant Death Syndrome (SIDS).
In addition to standard sleep sacks, there are also toddler-specific sleep sacks available. These are designed with pants-style legs instead of the typical sleeping bag-type pouch at the bottom. This design allows for greater mobility and can accommodate older children, with some brands offering sizes up to 5T.
When selecting a sleep sack, it is important to consider the room temperature and the number of layers needed. Generally, the recommended number of layers for sleep, or perhaps one additional layer, is sufficient for a comfortable night's rest. It is crucial not to overdress or over-bundle babies, as overheating can increase the risk of SIDS.

They can help prevent the startle reflex
Sleep sacks are wearable blankets designed to keep babies warm and safe while sleeping. They are beneficial for babies who are transitioning from being swaddled to using a blanket.
The Moro reflex, or startle reflex, is an involuntary response experienced by newborn babies. It is a normal occurrence that parents will notice their babies doing from birth until around 4 months old. The reflex is often a response to an outside factor, such as a sudden touch or movement, or it can be triggered when a baby feels as if they are falling. The Moro reflex is a protective mechanism, and the baby will flail their arms out and arch their back in response.
Sleep sacks can help prevent the startle reflex by providing a snug and secure environment for the baby. The baby's arms are free, so they can adjust their position if needed, but the sleep sack prevents them from flailing their arms and waking themselves up. The womb-like environment created by the sleep sack also helps to prevent the reflex, as it stops the baby from feeling the falling sensation that often triggers it.
Sleep sacks are particularly useful for babies who are transitioning from being swaddled. Swaddling is recommended for newborns as it provides comfort and security, and it prevents the startle reflex. However, once babies start to roll over, it is no longer safe to swaddle them, as it can restrict their movement and increase the risk of SIDS. Sleep sacks are a safer alternative as they allow the baby's arms to be free, so they can push themselves back onto their back if they roll over.

They are not recommended for babies who can roll over
Sleep sacks are not recommended for babies who can roll over. Once a baby can roll over, their hands should be free so that they can push themselves back onto their back. If a baby gets stuck on their tummy and can't use their arms to roll back over, they risk suffocating, which is a cause of Sudden Infant Death Syndrome (SIDS).
Sleep sacks are a good transition piece between swaddling and blankets for mobile babies. However, once your baby can roll over, you should transition them from a swaddle to a sleep sack.
The American Academy of Pediatrics (AAP) recommends keeping loose blankets and sheets out of a baby's sleep space for the first 12 months of life to reduce the risk of sleep-related injury. Sleep sacks are a safer alternative. However, this does not mean that loose blankets are the best option for toddlers and preschoolers. Blankets tend to shift around, especially with active sleepers, and can increase the risk of SIDS.
Sleep sacks can be used from day one, although many parents opt to use swaddles for newborns until they show signs of rolling, which is typically around 2-4 months of age. Once babies start rolling over, they should transition to a wearable blanket or sleep sack with their arms free.
If your baby is having trouble sleeping without the swaddle, there are sleep sack products designed specifically for transitioning out of the swaddle. These can be helpful for babies who wake frequently at night when their arms are free due to the Moro reflex, which typically begins to disappear starting at 12 weeks.
