What is a Sleep Sack?
A sleep sack, also called a wearable blanket, is a zippered or buttoned garment that is made to keep infants secure and warm while sleeping. Unlike blankets, which may put a child at risk of suffocation or overheating, a sleep sack is designed to keep an infant comfortably covered with security at all times.

When to Start Using a Sleep Sack
You can start using a sleep sack as soon as your baby is born, depending on the size and the type of sleep sack you want. For newborns most sleep sacks are made for babies, and these usually provide a snug, swaddle-like fit that helps them feel secure. Once your baby can roll over - generally by 3 to 4 months, they require a sleep sack that lets them move a little more while still ensuring safety.
Here are some general guidelines:
- Newborn to 3 Months: Swaddle sleep sacks or newborn-designed sleep sacks, often with some form of adjustment, help to provide a feeling of security to the baby, avoiding the startle reflex.
- 3 to 6 Months: once the baby is able to roll, transition to a larger, more spacious sleep sack with an arm that allows safe rolling without arm constriction.
- 6 Months and Over: Here, you can continue to use a fitted sleep sack suitable for their size as they grow. Look for sleeping sacks that allow more mobility, making them more comfortable, especially when you need to have them as toddlers.
Always ensure that the sleep sack is the right size for your baby. Avoid the instances when it is too loose or tight because these can affect their safety and comfort.
Factors to Consider When Choosing a Sleep Sack
When picking a sleep sack for your baby, consider these factors to balance both safety and comfort. Here are some important things to note as you decide which one is right for your little one:
Size: Match your baby's current size in selecting a sleep sack. A sleep sack that fits well is comfortable and safe. It should be fitted around the neck and armholes, leaving enough loose space on the body so that they can move about comfortably.
Fabric: Consider the sleep sack material as per season and according to your baby's comfort. Cotton works well for summer, and fleece or wool for winter. The selection of soft, breathable fabrics helps regulate temperature and prevent overheating.
Temperature Regulation: The sleep sack is designed for a season. Some have a TOG rating that indicates the level of warmth. Choose one suitable for your home's temperature so that your baby is not too hot.
Ease of Use: The sleep sack should have zippers or snaps to easily put it on and take it off. Some sleep sacks even come with a two-way zipper that can be used at night when the baby needs diaper changes.
Safety Features: The sleep sack should fit snugly around the neck and armholes so the fabric won't slip over your baby's face. Avoid sleep sacks with loose hoods or excess accessories that could pose a choking hazard.
TOG Rating: A TOG rating indicates how warm a sleep sack is. Some fabrics may feel thicker but have a lower TOG rating than thinner but warmer materials.
Comfort and Mobility: A sleep sack should have sufficient space for your baby to move about, which is very important around the arms and legs. Your baby will remain comfortable and continue healthy physical development as they grow.
Sturdiness: A high-quality sleep sack that can withstand a lot of washes is important, as babies go through multiple sleep sacks in short periods. Look for strong zippers and materials that retain their shape and softness.
Swaddle vs. Open Sleep Sack: When your baby is younger and has the need for swaddling, choose the sleep sack that features swaddles. When they grow and can roll over, switch to a sleep sack that offers more openness in terms of their movement and security.
When to Stop Using a Sleep Sack
Most experts recommend stopping the use of a sleep sack when your baby is around their first birthday or when they outgrow the largest size available, as this is usually when they are comfortable enough to transition to regular bedding while still ensuring safety against suffocation risks; however, you can continue using a sleep sack as long as your child seems comfortable and it fits properly, even into toddlerhood depending on the child's mobility and needs.
Key factors to consider when deciding to stop using a sleep sack:
- Size
If the baby has passed the maximum sleeping sack size in the market, it is about time to drop it.
- Comfort Level
If a child starts to feel uncomfortable wearing the sleep sack, then it is time to change that.
- Mobility
Once your child starts actively rolling over and trying to get out of the sleep sack, it might be time to move on.
- Developmental stage:
Most pediatricians advise against loose blankets in the crib until at least 1 year old so that a sleep sack can be a safe alternative until then.
Swaddling vs. Sleep Sacks
Both swaddling and sleep sacks are a way of keeping babies warm as well as safe during sleep, but they have different functions and safety information:
Swaddling
Swaddling, like with the Momcozy Baby Swaddle, involves wrapping your baby in a soft blanket to help it feel secure, reduce the startle reflex, and encourage self-soothing. It’s generally recommended to stop swaddling once your baby reaches around 12 weeks or starts rolling over, as it can pose a suffocation risk.
Sleep Sack
A sleep sack is a wearable blanket with a zipper, keeping the arms free. It is among the safest options for bedding, as it doesn't cover the baby's face or neck and allows the baby's body temperature to be regulated. Sleep sacks are best for older babies and toddlers who have more control over their movements. They should be discontinued once a baby starts crawling or attempting to escape from the crib.
Alternative Bedtime Attire for Infants
Though swaddles and sleep sacks are popular choices, there are other alternatives to keep your baby cozy and safe during sleep. Here are a few options:
- Baby Pajama
Baby pajamas are soft, breathable, and comfortable. Pajamas are wonderful options instead of swaddles or sleep sacks. Momcozy Baby Pajama has a unique BB-TEMP label that changes color with an increase in your baby's body temperature to adjust clothing and room temperature. The bamboo fiber construction is combined with two-way zippers and a hidden zipper design, ensuring your baby is warm and safe from suffocation. Zippers or snaps ensure easy diaper changes, while the snug fit offers safety and freedom of movement.
- Blanket Wraps
They share similarities with sleep sacks but offer increased flexibility. With open armholes, these wrappings provide convenience and safety when worn. Like sleep sacks, they also vary depending on the fabric in order to both warm the infant and ensure proper body heat.
- Simple Sleep Shirts
For warmer climates or when it's not too cold, a simple baby sleep shirt or gown is a breathable alternative. These are often made from cotton and keep babies comfortable while allowing free movement.
These alternatives provide a safe and comfortable way for your baby to sleep while removing all the risks from loose blankets. Choose the one that best suits your baby's needs based on the season and their stage of development.
