Many parents worry about safety when it comes to their baby’s crib. From loose blankets to bumper pads to thick mattresses, there are many dangers to avoid.
So what do you do when you want your baby to sleep safely and in comfort? How do you avoid loose bedding but ensure your baby will be warm enough on cold nights?

Best Transitional: Amazing Baby Transitional Swaddle Sack
- The TRANSITIONAL SWADDLE SACK allows baby to SELF-SOOTHE and promotes BETTER SLEEP and SAFER SLEEP; Perfect for babies who prefer to sleep with ARMS UP babies who are starting to rollover and babies able to break out of a traditional swaddle
- LITTLE SLEEVES with BIG PURPOSE; The 1/2-length uniquely-shaped sleeves with mitten cuffs closed provide partial suppression of Startle Reflex to help baby SLEEP BETTER and if baby rolls onto tummy baby can push up to reposition head to access air
- EASIEST way to wean from traditional swaddle; TSS is not a tight swaddle nor a loose sack; May seem small but SNUG FIT around tummy and shorter sack support legs in flexed position help baby feel secure to SLEEP BETTER; Can adjust neck size with zipper
- FOLDOVER MITTEN CUFFS MAY BE WORN OPEN OR CLOSED; Caregiver can open one or both cuffs so baby can SELF-SOOTHE or close the cuffs to PROTECT BABY FROM FACIAL SCRATCHES and provide partial suppression of startle reflex
Some parents prefer swaddles because they reduce the startle reflex in babies. Other parents prefer sleep sacks because they have a looser fit. Some sleep sacks fit babies well past swaddle stages.
What do you do if you want the best of both?
The Amazing Baby Transitional Swaddle Sack is the perfect combination and might be the right sleep sack for you. It’s an ideal choice for babies transitioning from a swaddle to a sleep sack.
This sleep sack features quarter-length sleeves with a flip-over mitten. When the mitten is flipped over, the sleeves reduce the range of motion in your baby’s arms. This prevents the sudden, jerky movements that often wake babies at night.
This sleep sack has the option of keeping the mittens open and your baby’s arms free. Or, if you prefer, you can just open one mitten without pulling their arm all the way through the sleeve. This limits the startle reflex while allowing them to suck on their hand during sleep.
The two-way zipper is designed to make middle-of-the-night diaper changes a breeze. Plus, this cotton sleep sack is made with breathable material to avoid overheating.
One thing to note is that your baby won’t be able to lower their arms during sleep. However, this isn’t always an irritation for babies. In fact, some babies prefer this sleep sack over restrictive swaddles.
The swaddle-like features make this the best sleep sack for transitioning from swaddles to sleep sacks.

The extra-long design will allow your baby to comfortably move their legs and hips. And if middle-of-the-night diaper changes are in need, the inverted zipper pulls up starting at the bottom.

FAQs
What should you look for in a baby sleep sack?
When deciding on the baby sleep sack that is right for you, there are several things you’ll want to first consider. Some good starting questions might be:
- Will I need a lightweight or heavyweight sleep sack?
- Will I want it to serve as a swaddle as well?
- Do I want a sleep sack that they can grow into or separate ones for each stage?
- Will I need to change my baby’s diaper in the middle of the night?
Once you’ve answered those questions, you’ll be able to make a more informed decision.
You might see something labeled “TOG”. This stands for thermal overall grade and will tell you how much warmth the fabric provides. The higher the TOG, the warmer the fabric is.
What are important safety considerations with a baby sleep sack?
If you find yourself asking, “Are sleep sacks safe to use?” Rest assured, knowing that the use of sleep sacks is approved by health professionals. The use of sleep sacks reduces the risk of suffocation compared to blanket use.
However, keep in mind that the National Instuitute of Child Health and Human Development warns that heavily layered babies are at an increased risk of sudden infant death syndrome. They urge parents to dress their babies appropriately for the temperature and watch for signs of overheating. Be sure to not overdress your baby when using a sleep sack.
When using a baby sleep sack, also ensure the sack does not cover your baby’s face. When laying them down, put your baby to sleep on their back to ensure proper breathing for safe sleep.
Are weighted sleep sacks safe?
Pleas note that on June 21, 2022, the American Academy of Pediatrics (AAP) issued updated safe sleep recommendations. Among these recommendations was a statement that weighted swaddles, weighted clothing and similar weighted objects on or near a baby are unsafe. Weighted sleep sacks presumably fall into this category and thus are not recommended.
