What is a baby sleep sack?
A baby sleep sack is like a wearable blanket that helps your little one stay warm while they sleep and provides an excellent alternative to blankets. Known to be hazardous to babies during naps and nighttime sleep, loose blankets are advised against in favor of sleep sacks. The American Academy of Pediatrics advises that babies should sleep on a firm mattress with a simple fitted sheet, wear clothes suitable for the room temperature, have no toys or additional objects in their crib and no loose blankets.
A good baby sleep sack is crucial in helping reduce the risk of Sudden Infant Death Syndrome (SIDS). Baby sleep sacks provide an excellent alternative to blankets as they keep your little one warm without the risk of suffocation or entanglement.
Most baby sleep sacks are made from soft fabrics like cotton and have zippers so that diaper changes can be done quickly and easily. They come in a variety of sizes, styles, and materials to suit different weather conditions and climates.
In addition, they provide added mobility and comfort while allowing enough breathability so that babies stay cool throughout the night.
Baby sleep sacks make sleeping safer, easier, and more comfortable for parents as well as their little ones!
Conclusion
When it comes to keeping your little one safe, secure and comfortable at night, baby sleep sacks are an excellent choice. From lightweight cotton fabrics perfect for warmer months to thick merino wool fabrics ideal for colder climates, there’s something available to suit every season and weather condition.
Plus, they provide plenty of breathability so that your baby stays cool and comfortable throughout the night. With so many great options available, you’re sure to find one that works for your family!
Frequently Asked Questions
How should I choose the best sleep sack for my baby?
When choosing a sleep sack for your baby, it’s important to consider the fabric material, size, and climate. Look for materials like merino wool and organic cotton that will provide plenty of warmth while regulating temperature. Make sure you get the correct size for your little one’s age and weight so as not to restrict their growth and movement. Also, remember the higher quality of the fabric the longer it will last.
If you are sleep training your baby you may like to take this into consideration when selecting a sleep sack. Read my article about the best gentle sleep training techniques.
Why are weighted sleep sacks no longer recommended?
The American Academy of Pediatrics (APP) states that weighted clothing swaddled on or near your baby isn’t safe and not recommended. Weighted sleep sacks have been found to be unsafe for babies as they can be too restrictive for babies’ movement.
Additionally, there is a risk of suffocation if the weight of the blanket becomes too heavy. It is best to opt for lightweight breathable fabrics.
What does tog mean?
Tog is a measure of thermal insulation and is used to indicate how warm a fabric or material will keep you. The higher the tog rating, the more insulated and warmer the fabric or material will be. Baby sleep sack ratings usually range from 0.5 to 2.5 and can help parents decide which sleep sack is most appropriate for their baby depending on the environment.
When should my baby stop using a sleep sack?
When your baby shows signs that he/she can roll over comfortably and stay in the same position for a period of time, it is safe to stop using a sleep sack. The AAP recommendation is to wait until they are at least one year old before introducing toys, pillows, loose bedding or quilts. Of course if parents or primary carers want to wait longer then that is their decision with many keeping their children in sleep sacks well into their third year.
At what age should my baby wear a sleep sack?
Sleep sacks are generally recommended for babies from birth to 6 months of age. It is important to choose the correct size and fabric material so that it is not too restrictive or heavy on your baby.
Choose sleep sacks designed specifically for your baby’s age as they can differ as your child grows. The American Academy of Pediatrics (AAP) recommends waiting until a baby is at least one year old before introducing toys, pillows, or quilts.
Can a 2 month old wear a sleep sack?
Yes, a 2 month old can wear a sleep sack, even if they are still in a bassinet by your bedside. Make sure to choose one that is specifically designed for babies of this age and size. Look for lightweight breathable fabrics like organic cotton or merino wool so that your baby stays cool and comfortable throughout the night. Additionally, check the fit and make sure it isn’t too tight.
Can I put my 1 month old in a sleep sack?
Yes, a 1 month old can wear a sleep sack. When selecting one make sure to get the right size and fabric material for your baby’s age and weight. Often parents prefer to swaddle their newborns but there are some excellent sleep sacks that combine with the swaddling concept too. Look for materials like organic cotton or merino wool that will provide plenty of warmth while regulating temperature.
Are sleep sacks safe for babies?
Yes, sleep sacks are considered to be safe and secure for babies when used correctly. They provide an alternative to blankets and can help reduce the risk of SIDS by providing a comfortable, warm cocoon for your little one. When choosing a sleep sack make sure you get the right size and fabric material so that it is not too restrictive or heavy.

Final thoughts
When selecting a sleep sack, make sure to get the right size and fabric material for your baby’s age and weight. Look for lightweight breathable fabrics that will provide plenty of warmth whilst regulating their temperature and fit your baby perfectly.
Additionally, consult with your healthcare provider about when it is time to transition away from using a sleep sack if you are concerned or would like further guidance.
Why should you trust me?
As a paramedic and mum of two I know that choosing sleep sacks for babies can be a minefield for parents! I know how important it is to create a safe sleep environment for babies so I always recommend that parents look for high-quality products that have been tested using the latest safety guidelines.
A happy sleeping baby is the ultimate goal so don’t be afraid to try out different styles and fabrics until you find the best fit.
