Factors to Consider When Buying a Sleep Sack

When choosing the top sleep sacks, we kept these factors in mind.

• First, we looked for sleep sacks with breathable fabrics that are soft to the touch. We wanted ones that would be comfortable against delicate baby skin and keep them warm without overheating.
• Second, we made sure each sack was adjustable so it could grow with your baby.
• Next, we looked for imaginative designs that will help keep your baby settled and cozy all through the night (such as weighted, swaddled, etc.)
• Finally, we looked at the TOG rating. The Thermal Overall Grade is a rating given to clothing, or as it’s commonly known, Thermals. The TOG rating represents how well the set of clothes insulates you from different weather conditions. The colder the weather, the better that item’s TOG value.

Other factors to consider included budget, style, and overall preferences. We hope you find one that fits perfectly in both style and comfort!

Best Sleep Sacks for Baby Overall-Halo Cotton Sleepsack Swaddle

Last update on 2024-05-05 / Affiliate links / Images from Amazon Product Advertising API

Of all the baby sleep bags I have used, I have yet to find one that compares to this Halo Sleep Sack Wearable Blanket. The Halo sleep sacks have been around for years and are still going strong because of their efficiency. 

This sack was my go-to for my nighttime routine when my girls were little, as it replaces loose blankets in the crib for a safer environment. Recommended by hospital nurseries, this sleep sack has been proven to help babies sleep better and longer. 

The double-knit construction is designed for perfect swaddling, and 100% cotton material is ideal for all seasons. 

This award-winning baby sleep bag has a sleeveless design to prevent overheating and an inverted zipper for easy diaper changes. 

It has a 3-way adjustable swaddle, so you can use Arms-In to help reduce startle reflex, One-Arm-Out for self-soothing, or Two-Arms-Out to transition baby to the SleepSack when they’re ready.

The softness of this sleep sack will quickly become one of the baby’s favorite snuggle companions, keeping him cozy day and night.

Suitable for ages 3-6 months with a TOG rating of 1.5, the sleep sack is lightweight enough for warmer climates yet solid, soft, and stretchy enough for cooler temperatures. 

However, consider adding an extra layer for chilly nights or outside visits in winter. My favorite part is the “back is best” embroidered design on the front to remind parents that newborns should sleep on their backs. 

What I Like the Most

• Light-weight
• Breathable sleep sack
• Hip Healthy Swaddle
• Machine Washable
• Affordable
• Crowd-pleaser

What I Dislike

Nighttime can be a real struggle for some newborns until they find Love to Dream Newborn Swaddle Up Sleep Sack. When babies hate being swaddled traditionally, this product can saved a parent’s sleep routine and sanity.

Unlike traditional swaddles, which bind a baby’s hands to its chest or sides, this swaddle creates a womb-like environment for your baby, heping them sleep better.

One of the stand-out features of this swaddle is its patented wing design. It allows the baby to keep their arms up and near their face, with ample room for movement, which many babies find comforting and soothing. 

Not only that, but it also helps prevent the startle reflex that can wake up babies and disrupt their sleep. It’s a game-changer for tired erants, as baby can sleep longer without waking up.

This sleep sack is made with a four-way stretch fabric, which is breathable and gentle on the skin while maintaining a snug fit. 

The TOG rating of 1.0 means it’s best for summer, but you can always throw another layer over or put them in a warmer pajama set to keep your little one warm during winter.

Best for Budget- Simple Joys by Carter’s Babies’ Microfleece Sleepbag

Last update on 2024-05-05 / Affiliate links / Images from Amazon Product Advertising API

Are you looking for the correct sleep sack that is comfortable, safe, and doesn’t break the bank? Look no further than this Carter’s Simple Joys Sleepbag!

For less than $20, you get a pack of two of these cute baby sleep sacks that I can’t just recommend enough! The 100% polyester keeps the baby warm and super cozy yet lightweight to avoid overheating like other expensive sleep sacks.

Also, it’s machine washable, making it easy to keep clean and maintain.

It has a zipper down the front, so you can quickly get your baby in and out of it. Bonus points for the safety tab to keep the zipper away from the baby’s chin and neck!

Though it says true to size, the sizing runs a bit small. So if you’re unsure which size to get, or if your baby is on the chubbier side, order a size up.

What I Like the Most

• Machine wash
• Durable
• Roomy for legs movement

FAQs

Still have questions? Let’s review a few commonly asked questions.

When Do Babies Start Wearing a Sleep Sack?

Most parents use a sleep sack when their baby is between two and six months old. I recommend using one when:

• Your baby starts rolling in his sleep (at this point, a swaddle is no longer safe).
• Baby begins to move their arms around in their sleep, potentially scratching themselves with their sharp little nails.
• When they start to pull off their covers, and would wake up cold if left uncovered (aka, toddlers). 

When Should Babies Stop Wearing Sleep Sacks?

The exact age at which your child no longer needs a wearable blanket or sleep sack will vary from child to child — some children may be ready as early as nine months, while others may need their wearable blanket until toddlerhood!

Are Baby Sleep Sacks Recommended?

Baby Sleep sacks are a great alternative to swaddles and traditional blankets as they reduce the chances of SIDS and suffocation while keeping the baby warm and comfortable. Unlike swaddles, a sleep sack provides just enough fabric to provide warmth without the risk of getting tangled up.

Are Baby Sleep Sacks Safe?

The American Pediatric Association recommends using a lightweight sleep sack instead of blankets or weighted sleep sacks when putting your baby to sleep since it reduces the risk of SIDS (Sudden Infant Death Syndrome) and suffocation.

It also encourages parents to put babies on their backs to sleep in a crib that meets safety standards, with no blankets, pillows, or soft objects. A sleep sack is safer than loose blankets and can help prevent overheating. 

What Aren’t There Any Weighted Sleep Sacks on the List?

From my own and many other parents’ experiences, weighted sleep sacks are tricky. If a baby likes to roll onto their belly (which is okay once they’re rolling independently), the weight is not well aligned. Plus, most are quite expensive and cumbersome, leaving many parents disappointed when they don’t work as promised.

Happy Sleeping!

A good sleep sack is a must-have baby gear for any parent. Ultimately, it all comes down to individual needs and preferences. A great sleep sack offers your baby quality sleep and peace of mind as a parent.
