5 Reasons To Use A Sleep Sack

Share on Facebook | Follow on Instagram:

Sleep time is crucial for babies as it plays a significant role in their overall growth, development, and well-being. Ensuring that you are providing the safest sleep environment to help support your baby’s growth and development is extremely important. We highly recommend parents use a sleep sack for their baby to support safe and productive sleep. If you are considering a sleep sack for your baby, here are our top five reasons why you should start using one today.

Ease of Use and Familiarity

Sleep sacks are much more straightforward than complicated swaddles or pajamas. Sleep sacks are convenient and easy to use, allowing for quick diaper changes without fully waking the baby. A sleep sack also provides a familiar sleep environment which is more likely to create more consistent sleep.

Body Temperature Regulation

Sleep sacks help regulate a baby’s body temperature during sleep, providing warmth without the need for additional blankets which can be a safety issue in their crib or bassinet. The best sleep sacks help to regulate your LO’s body temperature so that they do not wake during their sleep because they are too cold or too warm. We love the wool sleep sacks for nighttime sleep. 

Restriction for Crib Ninjas

A crib ninja is a little one who has become able to scale the crib surroundings. It is amazing how agile some toddlers can be! Using a sleep sack in the right way can help minimize the ease of access for clever toddlers to climb out of their cribs. 


Sleep sacks provide that ‘comforter’ feeling that most big humans like when sleeping at night. This allows the temperature in the home to be within an appropriate range of around 68-70 degrees (most of us sleep better with slightly cooler room temp). Not using a sleep sack can feel ‘exposing’ for a baby. This is comparable to us grown ups just having one layer of clothing or a sheet when we sleep. The sleep sack provides just the right amount of cozy cuddle to help the little one sleep longer and better. 

The first four reasons should all be enough to get you to order a sleep sack for your little one. However, number one on our list is the most important, and really the primary reason to start using a sleep sack.


Sleep sacks are properly secured to baby or toddler and should not move to a position that is unsafe, potentially covering the child’s face or neck. Blankets can easily move as your child moves throughout the night. Sleep sacks reduce the risk of suffocation and Sudden Infant Death Syndrome (SIDS) by providing a safe alternative to loose bedding like blankets and sheets.

We hope this deep dive into sleep sacks has been helpful. We know how important good rest is for babies and their caregivers.
