Not every swaddle is made equal!
Plenty of evidence shows that swaddling, when used correctly, can be a tremendous way to promote safe sleeping. The Safe Sleep Guidelines from the American Association of Pediatrics are clear: swaddling helps to keep babies on their back, which is the ideal sleep position to assist in preventing SIDS (Sudden Infant Death Syndrome). Since the guidelines also recommend that there be no blankets, pillows or bumper pads in the crib, your baby needs to be swaddled in a correct and optimal manner. Properly done, the swaddle will stay in place, keeping baby safe and comfortable.
Some of the other benefits of swaddling?
- Improved sleep for baby and for parents
- Decreases the Moro startle reflex, in turn increasing REM sleep, which is vital for brain development.
- Reduces colic and fussiness: a happy baby is a calm baby.
- Prevents over-stimulation and helps your little one feel comforted by mimicking the comforts of the womb.
Temperature regulating fabric
Fabrics that retain too much heat will only be uncomfortable at best and dangerous for baby, at worst. A baby’s body isn’t yet set up to regulate their own temperature perfectly and their small size means that they can quickly become overheated. Look for a moisture wicking fabric—as you would find in some sportswear—that will keep baby warm and dry, without overheating.
Flexible fabric
While some people worry that swaddling can interfere with proper hip development, among other joints, what you need to look for is a swaddle with fabric that has enough give to allow the hip joints to move freely without interfering with the comfort and safety benefits of the swaddle.
Avoid swaddles that restrict hip movement, as they can result in your baby developing hip dysplasia. Your baby needs free range of motion in their hips and legs to keep their joint development on track. The swaddle needs to be tight at the torso, but not below. It can still be perfectly safe, if bands are used below baby’s feet.
Don’t forget to band
Banding the swaddle below the feet is absolutely necessary, even as your baby grows, to ensure a snug and secure fit. What you don’t want is the fabric rising during sleep, potentially covering your baby’s face and creating a suffocation risk. Banding the excess fabric below baby’s feet ensures this won’t happen.
Swaddle sizing
A swaddle should fit so that your baby can have their shoulder above the top edge of the fabric when placed on the swaddle. This may seem a little counter-intuitive in that you might think that keeping the shoulder below the fabric line will keep baby more snuggly wrapped, but this actually poses the risk of suffocation if the fabric ends up in your baby’s face. Keeping the swaddle below the shoulders also ensures that no constraint is put on the shoulder joints.

The Ollie Swaddle extends the duration of sleep for all babies (including preemies and high risk), reduces fussiness, and helps baby self-calm. The elasticity allows for freedom of movement while the opening at the bottom makes it easy to change diapers. The Ollie Swaddle helps ensure your baby is content and getting the sleep they need. Ollie Swaddle’s patented moisture-wicking material supports the health and development of your little one from day one. The luxuriously soft and gentle feel keeps your baby tightly swaddled while regulating their temperature to keep them comfortable and cool, which reduces the risk of overheating.
