Weighted Sleep Sack For Baby – Are They Safe and Do They Work?

Weighted sleep sacks and weighted blankets are becoming more popular. Do you need a weighted sleep sack and will it help your baby sleep better? This post will explain what a weighted sleep sack is, the purpose, and discuss whether it will help your baby sleep better.

What Is a Weighted Sleep Sack and Its Purpose?

A weighted sleep sack is just as it sounds. It a form of sleep sack that has a little weight to it. But, why would a sleep sack need weight added to it?

These sleep sacks and blankets can calm your nervous system and help babies feel like a hand is on them. This gives them a feeling of reassurance by acting like a hug with a technique called deep pressure stimulation. Just like swaddling helps newborns sleep better, a weighted sleep sack can possibly help your baby sleep better, too. But, does it always work?

Will It Help Your Baby Sleep?

Swaddling your baby keeps your baby sleeping longer when their Moro reflex is strong. But, as your baby gets older and you stop swaddling, do you still need a special type of blanket?

Sleep sacks are safe ways to have a wearable blanket so your baby won’t suffocate. So, sleep sacks are definitely a great investment!

Does the sleep sack have to be weighted?

Not necessarily. A weighted sleep sack can help some babies sleep longer, however. Here are a few types of babies we find can possibly benefit from one:

  • If your baby likes when you put a hand on them.
  • Your baby seems fussy and/or nervous a lot.
  • Your baby still has the Moro reflex but is breaking out of the swaddle or doesn’t like to be swaddled.
  • You suspect your baby or toddler has sensory processing challenges.

Of course, as with many tools in your parenting toolbox, sometimes you just have to experiment to find what works for your baby! Many products may improve sleep but some sleep problems can’t be solved with sleepwear, of course. So, whether your baby sleeps better depends on the reasons your baby is waking in the first place.


Weighted sleep sacks are considered safe as long as the weight isn’t more than 10% of your baby’s body weight. So, if your baby is 10 pounds, the sleep sack should not surpass one pound. And, if your baby is 20 pounds then your sleep sack should not surpass two pounds. As a reminder, you should always choose products that meet or exceed the United States Consumer Product Safety Commission standards and have been tested for a multitude of harmful substances. Be sure to check the safety page on a company’s website for any product you use for your baby as well as check with your pediatrician since they know your baby best.

Dreamland Weighted Sleep Sack

I learned about the Dreamland Weighted Sleep Sack recently and they were kind enough to send me a couple of samples to review. These products are truly top-notch and packaged beautifully! The material is soft and it feels like a superior product compared to many of the sleepwear products out there. Of course, my first question with a newer product is whether it’s safe for your baby. This sleep sack is doctor-approved, exceeds CPSC standards, and is OEKO-TEX® certified. Dreamland Baby Co has a swaddle, sleep sack, and blanket option. The blanket was one of the best I’ve seen and I wanted to wrap myself into it right away! I come across many baby products and I can confidently recommend this one in a heartbeat.

Nested Bean Weighted Sleep Sack

There is one other sleep sack worth mentioning and that is the Nested Bean Gently Weighted Sleep Sack. This is weighted differently, however, with just a light weight on the chest. This mimics your hand on your baby’s chest which is soothing for some babies out there though not all. It’s a good alternative if your baby seems to like that a lot. These two products are different approaches to helping your baby sleep better so your baby’s preference will be a big indicator as to how well they each work (or not).

In conclusion, a weighted sleep sack can be a good option for babies who are fussier and may need some added comfort. I certainly wish I had these products to try out with my son when he struggled with sleep! Of course, maybe then I wouldn’t have created this website. My goal is to help you solve your sleep problems much faster than I did and I hope this helps!

Zipadee Zip vs Nested Bean Zen Sleep Sack – Which Is Best for Better Sleep?

The Zipadee Zip vs Nested Bean – both the Zipadee Zip Swaddle Transition Sleep Sack and the Nested Bean Sleep Sack are great products. But, do you need both? Is one better than the other for your baby’s sleep?

In this blog post, you’ll learn about both products and which we recommend!

Zipadee Zip Swaddle Transition Sleep Sack

zipadeezipWe have been recommending the Zipadee Zip for a long time even before they were on the Shark Tank. The Zipadee Zip, created by a company named Sleeping Baby, is a really great invention to help your baby sleep better when it’s time to stop swaddling.

The “wings” of the Zipadee Zip stop your baby from feeling like they are falling when the Moro reflex is still strong. Many babies are ready to transition away from the swaddle before the Moro reflex has gone away, which is where the Zipadee Zip shines. It is safe for sleeping especially when a baby is rolling over and otherwise can’t be swaddled. And, it’s also good for when your baby doesn’t like to be swaddled, yet can’t seem to stay asleep without it.

If your baby has eczema or otherwise scratches herself, the Zipadee Zip will protect the skin. I was always terrible at keeping my baby’s fingernails clipped!

There are many different styles to choose from for the Zipadee Zip. And, although you won’t need the wings as your baby gets older, so many babies like this sleep sack that they make toddler sizes as well!

Nested Bean Sleep Sack

The Nested Bean products are very innovative with the simple premise that sometimes you just need a hand on you to feel comfort. That’s what their lightly-weighted products emulate: the feeling of a parent’s hand on your baby. Of course, there’s no perfect replacement for your hand but it’s a great concept!

While Nested Bean has a few different products, the one you’d compare to the Zipadee Zip would be the Zen Sack which is a sleep sack you use after you’re done swaddling.

The Nested Bean Zen Sack has a 2-way zipper and is lightly weighted with non-toxic poly beads to give just the right amount of pressure on your baby’s chest. Or, you can flip it over if your baby is a tummy sleeper though Back is Best to reduce the risk of SIDS. This sleep sack is made with 100% soft, breathable cotton with a 0.5 TOG. This means it’s lightweight which is very versatile.

Zipadee Zip vs Nested Bean Sleep Sack – Which is Better?

Both the Zipadee Zip and the Nested Bean Sleep Sack are great sleep sacks. But, which is better for your baby’s sleep?

We have worked with families who have used both and clients love both products. As a sleep consultant for over 10 years, I can tell you that either product would be a good choice. We give the edge to the Zipadee Zip simply because many babies won’t sleep better with the “hand on the chest” concept. Most of the babies with which we work need to be picked up to be soothed. We do love the concept but it only seems to “work” for some babies. Therefore, it simply functions as a regular sleep sack. There’s nothing wrong with that, of course, but if the weight doesn’t “work” it loses its special-ness. Therefore, we highly recommend the Zipadee Zip for many babies, but there are a few things to consider first:

  1. Does your baby use a pacifier?
  2. Does your baby like to suck on their thumb, fingers, or hands?
  3. Does your baby like to crawl around while self-settling to sleep?

If you answered no to all of these questions, the Zipadee Zip is an excellent choice!

However, if you answered yes to any of these questions, the Zipadee Zip may or may not be the best sleep sack for your baby. And, for that reason, you might choose Nested Bean or another sleep sack. We have a list of the Top 10 Best Sleep Sacks here.

Baby Likes to Suck on Thumb, Fingers, or Hands

If your baby likes to suck on their thumb, fingers, or hands, it may work out fine. Some babies will simply suck their hands through the cloth of the wings. But, if your baby likes to really feel their fingers or thumb inside their mouth mimicking a nipple, this might not work out very well. Some babies will adapt while others will struggle. This can lead to excessive crying during sleep training.

Baby Has a Pacifier

Some babies suck on their pacifier as they fall asleep but then don’t need it again. That would make using the Zipadee Zip work out just fine.

However, some babies struggle with self-settling when they can’t maneuver their own pacifier. We want your baby to be able to wake up between sleep cycles, find their own pacifier, and pop it back in. For these babies, we’d recommend a sleep sack with hands out such as the Zen Sack or the Bitta Kidda with a built-in lovey attached.

Baby Likes to Crawl Around or Stand Up

If your baby likes to crawl around the crib as they are self-soothing or stand in the crib, they may prefer to keep their hands free. We haven’t heard many complaints about the Zipadee Zip in this regard, so it’s a minor issue but depending on your baby, it is something to consider.

Zipadee Zip vs Nested Bean – Which to Buy?

If you still don’t know which product to buy and can’t afford to try both, I highly recommend you start with the Zipadee Zip. This is based on over 10 years of working with families and getting reports about which products their babies love. I know based on the experience of many families that your baby is most likely going to LOVE it!

Of course, your baby’s sleepwear is only one variable that impacts your baby’s sleep. And, that’s what we do here at The Baby Sleep Site!

Modern Toddler Bedding

If you have a toddler, it’s important to make sure that you are getting them some comfortable bedding. This will help encourage them to drift off to sleep. Getting the right amount of sleep can create a range of benefits. For example, you’ll be able to encourage healthy growth, improve their attention span, and help them learn new information. Let’s look at some tips that you can use to find the perfect modern toddler bedding.

Choose a Design That Appeals to Your Toddler

One of the biggest benefits of modern bedding is the number of designs that are available for you to choose from. There are dozens of stunning colors and images for you to explore. In some cases, you might want to take your toddler with you when you are shopping. Then, you can allow them to pick out the one that appeals to them most. By doing this, you’ll be able to get something that they will feel excited to sleep on. This can help make the transition to a bigger bed easier.

If you want, you might use the bedding they select as the basis when designing the room. For example, if they choose a green quilt filled with dinosaurs, you might want to paint the walls green. You can also use it to inform the type of furniture you choose, matching the colors or theme of the bedding. This can help you make sure that the room has a cohesive style. When making these design decisions, you can consult your child. By doing so, you’ll be able to make sure that they feel comfortable in the space.

Save Money with a Kit

There are a few important pieces of bedding that you’ll need to get for your toddler. Often, you’ll want a sheet, comforter, and some pillowcases. If you purchase each of these items separately, you might find that you need to spend a significant amount of money. Thankfully, this doesn’t have to be the case. Instead, you can purchase these items as part of a kit. In most cases, this kit will include a fitted sheet, a flat sheet, a pillowcase, and a comforter. By bundling all these items together, you’ll often be able to save a lot of money. You’ll also be able to make sure that all the designs match. It might be a good idea to get a few kits. This will ensure that you’ll be able to have one set in the wash, while the other is on the bed.

Pick the Right Pillow

When deciding what bedding you want to get, it’s important to make sure that you’re choosing the right type of pillow. There are several reasons why this is crucial. First, it will help ensure the right amount of spinal support. It will also ensure that they feel comfortable, helping them fall asleep faster. However, if they are under 18 months old, you might want to avoid introducing a pillow, as this might be a potential choking hazard.

There are dozens of pillow options available for you to choose from. However, it’s important to consider your child’s unique needs to make sure that they get the right pillow. First, you’ll find a range of different materials. It’s often best to try to find something that will be hypoallergenic. This will help limit the number of bacteria that can grow on the pillow, keeping your child safe. It can also be a good idea to get memory foam filling, rather than feathers or hemp. It’s best to avoid pillows filled with small pellets, as they might pose a choking hazard if they break.

You might also want to consider how firm the pillow will be. It’s often best to get something soft enough to remain comfortable but firm enough to offer spinal support. Finally, you’ll need to get a pillow that’s the right size. In most cases, toddler pillows will be between 13 to 18 inches.

As you can imagine, it’s easy to become confused by the number of options and brands available for you to choose from. Thankfully, there are some tools that you can use. For example, check out this informative comfy and safe toddler pillows compilation.

Choose a Mattress Protection

As your toddler gets older, you’ll want to move them out of the crib and into a bed of their own. As you do this, you’ll often need to purchase a new mattress. Though this can be a big investment, it will ensure that they get the spinal support that they need. To make sure that this mattress will last for a long time, you might want to use a mattress protector. These are thin sheets that can help protect the mattress from any spills. This will ensure that the water doesn’t seep through to the mattress, which can cause mold. It will also make cleaning up messes easier. Typically, a mattress protector will only cost around $50. Compared to the costs of paying for a new mattress, this figure is negligible.

Consider the Materials

It’s important to make sure that you’re getting the right type of materials when picking bedding for your toddler. This will allow you to get something that will be appropriate for both summer and winter. During the warmer temperatures, you’ll often want to get cotton. This will be a lighter material, allowing air to flow through it, keeping them cool. However, as the temperature starts to fall, you might want to turn to wool. This traps hot air, making sure that your toddler is kept toasty and warm during the winter months.


Choosing the right toddler bedding is very important. It will impact how comfortable your toddler feels in their bedroom, helping to make the transition from bed to cot easier. You will also be able to help them get the spinal support they need, keeping them healthy as they grow. So, use these tips to make sure that you’re picking the right modern toddler bedding.

Second-Hand Mattresses Could Increase The Risk Of Cot Death

It’s a common tradition in many families to pass down a mattress from one infant to another. While this tradition still occurs, a 1997 study indicates just how harmful this practice can be, and newer research has surfaced which shows similar findings.

According to the latest research, babies that sleep on mattresses previously used by other infants have a higher chance of falling victim to cot death. In fact, as per this research, of the 131 cases of cot deaths, more than half of the infants were believed to be sleeping on used mattresses that had been passed down to them from family members.

The same can’t possibly be said of a gently used mattress, can it? Interestingly enough, the study also revealed that the mattress was more often than not, used previously by babies who lived in an entirely different household.

So, factors such as the mattress coming from another household, the conditions under which it was used, and the number of infants that slept on it, could also play a role in its potential to be a health hazard, and this will be explored below.

If you’re thinking of saving some money by getting a used mattress for your little one, consider the following.

What is Sudden Infant Death Syndrome (SIDS)?

Each year, over 500 babies lose their lives suddenly and this occurrence is often blamed on cot death. Cot death or Sudden Infant Death Syndrome (SIDS) is the unexplainable sudden death of infants who are less than a year old.

Oftentimes, the death remains unexplainable even after a thorough autopsy has been performed and the scene has been carefully examined.

Second-Hand Mattresses And SIDS

According to a case-controlled study done in Scotland between 1997 to 2000, the use of a second-hand baby mattress can significantly increase the risk of SIDS, especially if the mattress is coming from another household.

The research shows that the risk is more pronounced if the bed was initially slept on by an infant who passed away due to SIDS before the mattress was passed on, or if the mattress was utilized by more than one infant during its lifespan.

The participants in the study were asked to fill in a questionnaire that includes information on infant care practices, such as details on co-sleeping habits on the day and/or night of death. This is in addition to the infant and family’s overall social and medical data.

As believed by some researchers, a toxic bacterium that is feared to be linked with cot death is found on second-hand mattresses.

While the research does reinstate certain points brought out in the initial 1997 study, there is a gap in the evidence that prevents the researchers from wholly attributing sudden infant death syndrome to old mattresses. Suffice to say, the cause and effect relationship between old mattresses and SIDS has not yet been fully established.

But, there’s a valid association between the use of second-hand mattresses and an increased rate of SIDS which parents cannot afford to overlook.

Mattress Solutions For Infants

As a parent, this research may seem a tad bit overwhelming. Your natural parental instinct would be to get rid of the second-hand mattress to ensure your infants’ safety. Despite the inability to establish a cause and effect relationship between second-hand mattresses and SIDS, it is advisable to ditch the old mattress and opt for a brand new mattress for your baby, especially if the used one came from another home.

Buying a new mattress would be the best option, even though some doctors have stated that used mattresses are probably not to blame for SIDS, it’s better to be safe than sorry.

Also, be sure to always apply the following requirements by doctors to ensure that your baby’s mattress is safe to use:

1. Mattresses need to be clean:

As a specific requirement, infant mattresses must be cleaned regularly. The suggestion is to buy mattresses with removable and washable PVC covers. The removable covers make it possible to clean the mattress easily and effectively.

With PVC mattresses, each baby born in a house need not have an entirely new mattress. Parents’ ability to wash PVC mattress covers means that they can keep the baby’s mattress clean for longer.

2. Mattresses ought to be sturdy:

For infants, it’s recommended that mattresses shouldn’t be saggy and overly soft. Doctors suggest that new-born babies should sleep on firm and sturdy mattresses. The used mattresses that were found in studies to cause SIDS could have become overly soft over time.

This could be a possible reason why mattresses passed down from one home to another could have been blamed for the cot deaths.

3.Mattresses must be new looking:

While it need not be a spanking new mattress, the mattress must not look dated or aged in any way. Mattresses that show signs of timely deterioration should be thrown away and never reused for infants, as the wear and tear might be a possible health hazard.

4. Babies should sleep on their backs:

For years, elders have recommended that new-born babies sleep on their backs to avoid SIDS. It seems that there is some wisdom to this, as it has been shown to be the safest and most comfortable sleeping position for baby.

Also, your little one’s cot should be free of any soft toys and excess blankets that might accidentally obstruct their breaking. Taken together, these measures can be very effective at preventing cot deaths.

From the research, it’s evident that much of the power to prevent SIDS is on your hands as a parent. Firstly, you must be aware of all the qualities of the particular mattress that you’re putting your baby to sleep on.

Pay attention to everything and be observant when your baby sleeps. Remember just as you would have the best sleep on a good, firm mattress, your baby is no different. Be aware of the type and quality of the mattress that you buy for your baby as well.

Trust us, your baby is a new mattress away from the best possible sleep ever, and you’ll have peace of mind knowing that their chances of going through SIDS is exponentially lower.

This research should never scare you, but should rather empower you to make informed choices when it comes to the wellbeing of your baby.

Top 10 Best Sleep Sacks for Baby’s Sleep

Parents are often concerned about whether their baby is too cold or too hot to sleep well. And, we want babies to sleep as much as possible. When it’s time to stop swaddling your baby, we advise you to transition to a sleep sack. Here are the top 10 best baby sleep sacks that can help your sleep better, in no particular order.

Zipadee-Zip Sleep Sack

We have been recommending the Zipadee-Zip for a very long time. It’s a great swaddle transition product because your baby will likely feel more secure, allowing them to sleep better at night and at nap time. The primary feature of the Zipadee-Zip is the “wings” that cover your baby’s hands without restricting movement. There are many sizes and patterns available for purchase. The product is of great quality, and we have heard many clients rave about this sleep sack!

Woolino 4 Season Sleep Sack

The Woolino 4 Season Ultimate Baby Sleep Bag Sack has been a top seller for over a decade, and for good reason. Merino wool is very soft, hypoallergenic, and temperature regulating. This award-winning sleep bag isn’t cheap; however, you won’t need to buy separate sacks for different seasons, AND you can use this sleep sack until the age of 2 years old. That means you won’t have to buy a new size every few months like with some of the others. It also has four shoulder snaps and a 2-way zipper for easy dressing and diaper changes. Highly recommend this sleep sack!

Love To Dream Swaddle Up

If you are in the market for a sleep sack but you aren’t sure whether your baby is ready to stop being swaddled just yet, the Love To Dream Swaddle Up Transition Bag is a great choice! It has patented zip-off “wings” so you can easily and gradually help your baby adjust to the “freedom” of being unswaddled. If necessary, you can zip on and off the wings to guide your baby to a sleep sack over time. According to most newborn sleep patterns, your baby will be ready to be unswaddled between 3 and 6 months old. Once you are ready to permanently lose the swaddle, simply keep the wings off for an easier transition.

Halo Sleep Sack

The HALO Sleepsack is a classic, and a great sleep sack for babies. The most notable feature of the HALO Sleepsack is that it has a double zipper to make diaper changes easier. The sleep sack is made from polyester micro-fleece and is sleeveless to reduce the risk of overheating. And, it comes in a variety of sizes, from baby to toddler, as well as colors. It also comes with a reminder to put your baby on their back to sleep. We think this sleep sack is a solid choice, and it’s not as expensive as some of the others.

Bitta Kidda Sleep Sack

The Bitta Kidda Soother Sleeping Bag is very innovative. It is unsafe to have anything loose in the crib with your baby until they are at least a year old. But, this sleep sack comes with an attached lovey, which can help your baby learn to self-soothe without being able to lose the lovey, or throw it out of the crib. This is perfect for tactile babies like my second son once you start sleep training. This sleep sack also has a patent-pending diagonal zipper to make diaper changes easier, but not so easy that your baby can unzip it themselves. This can become an issue as your baby becomes a toddler who wants to skip a nap. There is also an internal diaper cover similar to a onesie so the sleep sack moves with your baby. Very clever!

Burt’s Bees Wearable Blanket

The Burt’s Bees Wearable Blanket is nothing fancy but highly-rated. It is 100% cotton, comes in a variety of colors and patterns, and has a double zipper for easier diaper changes like many of the others. The price is right, and if your baby doesn’t need any “bells and whistles,” this is a great way to have a safe blanket on your baby. Keep in mind, it isn’t the warmest of blankets, so be sure to dress your baby appropriately and set the room temperature to be conducive to sleep

Simple Joy’s by Carter’s Sleeping Bag

These wearable blankets, Simple Joys by Carter’s are another highly-rated 100% cotton sleep sack we recommend. There is a tab on the sack that covers the zipper to keep it away from your baby’s chin and neck. That makes it harder for your toddler to unzip it (which can become a problem). These are definitely budget-friendly, given they are sold in a pack of 3, and will get the job done! The biggest drawback is finding these in larger sizes.

Amazing Baby Transitional Swaddle Sack

The Amazing Baby Transitional Swaddle Sack is another product that can help your baby transition from swaddle to sleep sack more easily. The mitten cuffs cover your baby’s hands, which will gently suppress the moro reflex. But, it is not as restrictive as a swaddle. This means if your baby rolls onto their tummy, they can use their arms to lift themselves up, which is important for safety. You can take one or both mittens off to allow your baby to self-soothe by using their hands and fingers. As with most of the others options, this sleep sack has a 2-way zipper to help with diaper changes and is 100% cotton.

TILLYOU All-Season Micro-Fleece Baby Sleep Bag

The TILLYOU micro-fleece baby sleep bag is another all-season sleep sack, according to the manufacturer. This sleep sack comes in a variety of sizes and also has the double-zipper with a cover at the top to protect your baby’s skin. This is not a fancy sleep sack and comes in basic colors. If you like simple, this is a great choice for you and your baby.

Hudson Baby Muslin Sleeping Bag

The Hudson Muslin Sleeping Bag is another basic sleep sack made of muslin cotton. Muslin cotton is a more breathable cotton which is likely best in a warmer climate. This sleep sack comes in a variety of unisex patterns so you can use it with multiple children. These are another budget-friendlier option without bells and whistles.
