Are Weighted Sleep Sacks Safe for Babies? The Best Alternatives for Your Child’s Safety

You’ve likely heard about weighted blankets for adults – they provide gentle pressure that’s meant to reduce stress and promote better sleep. Well, a weighted sleep sack takes that same cozy concept and scales it down for babies and toddlers.

These wearable blankets have extra weight distributed throughout, ranging from a few ounces to around 1.5 pounds. The added weight mimics the soothing sensation of being cuddled or swaddled. It’s like getting a constant, gentle hug to help your little one settle in and snooze more soundly.

But given the pressure being applied to your baby’s chest, are weighted sleep sacks safe for use? In this article, I’ll break down the opinions of experts and regulatory bodies, and share the best alternatives to help your little one sleep soundly and safely.


Who Am I?

Why You Should Trust Me

Hello! I’m a mom of one, and I’ve only used a normal sleep sack for my daughter when we were in Germany, fighting the cold winter.

Back in Singapore, I didn’t use a sleep sack as I didn’t see a need to. However, in Germany, the cold winter meant a really cold room, and I felt the need to get my daughter a wearable blanket to keep her warm at night.

Since I did not use a weighted sleep sack, I sought help from 24 fellow mommies who did!

Out of 24 mommies, only two used weighted sleep sacks, while the others used normal ones. 

I also spoke to 3 sleep experts to better understand how sleep sacks help, or not, a baby to sleep better:


Weighted sleep sacks have gained immense popularity in recent years due to their purported ability to soothe and calm babies, promoting better sleep. According to NPR, manufacturers claim that the gentle pressure provided by the added weight in these sleep sacks can mimic the comforting sensation babies experience when being held, potentially reducing anxiety and promoting a sense of security.

Many parents have also reported positive experiences with weighted sleep sacks, claiming that their babies sleep longer and more soundly after using these products. With the desire for better sleep, especially among exhausted new parents, weighted sleep sacks have undoubtedly garnered much interest globally.


Are Weighted Sleep Sacks Safe?

Safety Concerns

While weighted sleep sacks have gained a devoted following, they have also faced scrutiny from medical experts and organizations. As of the publication of this article, the American Academy of Pediatrics (AAP) and the United States Consumer Product Safety Commission (CPSC), the independent federal regulatory agency that protects the public from unsafe products, advise parents against using weighted sleep sacks for their children.

The added weight could place too much pressure on a baby’s developing chest and lungs, increasing the risk of suffocation or impaired breathing. Additionally, the deep sleep promoted by these products could make it harder for babies to rouse themselves, posing a potential risk for Sudden Infant Death Syndrome (SIDS).

Furthermore, according to Anahita, one of the experts we spoke to, scientific research on the efficacy and safety of weighted sleep sacks for infants is limited. While a few small studies have looked at weighted blankets in NICUs, these don’t necessarily prove safety for at-home infant use. As such, she has expressed her reservations about using weighted products for children under 4 years of age.

Factors to Consider When Choosing a Sleep Sack

How to Choose a Sleep Sack
Top 3 Considerations When Choosing a Sleep Sack

The top three considerations when mommies choose a sleep sack are:

  • TOG rating 
  • If it regulates the baby’s temperature
  • Whether it is soft and cool to touch

Other considerations include brand, design, long mileage and price.

Top Consideration: TOG Rating

The Thermal Overall Grade (TOG) rating is a universally recognized measurement that indicates how warm the sleep sack will keep your little one.

A lower TOG rating indicates a thinner material, which is more appropriate for warmer temperatures. Such sleep sacks are known as lightweight or summer sleep sacks. On the other hand, sleep sacks with a higher TOG rating are thicker and would be more comfortable for your little one during winter.

According to Love to Dream, a sleep sack with a 0.2 TOG rating is suitable for room temperatures between 24°C to 27°C, while a sleep sack with a 3.5 TOG rating is suitable for room temperatures below 16°C.


Mommies whom we surveyed mentioned that they prefer sleep sacks that are breathable and gentle on the baby’s skin. They also mentioned that easy-to-clean, machine-washable sleep sacks are ideal since they would help save a lot of time.


It’s the top priority of reputable brands to ensure that your little one is always safe and comfortable, giving you the peace of mind you need as a parent. Moreover, these brands are often highly reviewed and recommended by other mommies who have already experienced the benefits of their products.


Investing in a sleep sack that fits snugly around your baby’s shoulders and arms is crucial for their safety and comfort. With a properly fitting sleep sack, you can rest easy knowing that your little one won’t slip inside and potentially suffocate. Hence, when choosing a sleep sack for your baby, ensure there’s enough room for your baby’s hips and legs to move freely, without being overly loose or tight.


The design may not be the primary concern with baby products, but some smart design features can be really handy at times! For example, look for sleeveless styles for when babies start rolling, zippers for easy diaper changes and closed bottoms to keep feet toasty.

Moreover, visually appealing designs can add a touch of joy to your daily routine with your little one!


If you decide to use a weighted sleep sack, choose one with the appropriate weight for your baby’s size and age since many sleep sacks come in different weight options. You should also follow the weight guidelines provided by the manufacturer of the sleep sack.

Moreover, you should opt for a sleep sack where the weight is evenly distributed and the pressure is applied gently to your baby’s body without causing discomfort or restricting movement.


Final Thoughts on Weighted Sleep Sacks

Concluding Thoughts

Overall, I think weighted sleep sacks aren’t worth the potential risk. Our babies’ safety has to come first. There are plenty of other safe alternatives like non-weighted sleep sacks and pajamas which can help our little ones sleep soundly without adding weight.

Should you choose to use a weighted sleep sack, I recommend weighing the pros and cons, and constantly monitoring your child while they’re sleeping before trusting the sleep sack.

I hope that through this article, you were able to find a sleep sack that suits your needs and lifestyle!
