When many of us were children, we went to bed at night in a crib full of fabric bumpers, cozy blankets, and loads of stuffies. Now, sleeping safety guidelines for infants have undergone a significant transition. 

This is why so many of us end up adding sleep sacks for babies to our registries. 

Sleep sacks aren’t just cozy and helpful; they’re also a crucial tool for creating safe infant sleeping habits. That’s why they should become a regular addition to your baby’s bedtime routine. 

The CDC has spoken against loose bedding, but it doesn’t mean you can’t still provide your newborn with the comfort and warmth they need during bedtime.

By choosing one of the ten wearable blankets mentioned below, you can feel confident that you’re helping to create the perfect sleep space for your little one.

Say No to Blankets: Understanding the Importance of Sleep Sacks for Babies

Whether you’re setting up a baby registry or shopping for one, baby blankets are always a popular baby shower gift. They’re soft, cozy, and so adorable. The funny thing is that your infant shouldn’t be using one alone at night. 

Per the American Academy of Pediatrics (AAP), each year, approximately 3,600 babies will die while sleeping. Many of these deaths result from suffocation or strangulation due to loose bedding and blankets in their crib

Research even shows that blankets and bedding can increase your child’s risk of SIDS. 

These are heartwrenching statistics but also something every new parent needs to know.

It’s understandable that you’d want to create a comfortable space for your little one to sleep in. No matter how soft and lovely loose blankets might be, they’re a serious risk factor.

With the creation of sleep sacks for babies, often called wearable blankets, you can still offer your baby comfort and warmth without the added dangers.

What Should You Look for In a Wearable Blanket for Your Little One?

When it comes to sleep sacks for babies, the number of options available is kind of overwhelming, to be honest.

Adding a sleep sack to your baby registry checklist can quickly go from fun to confusing. Don’t start stressing, though, there are several factors you can weigh to help determine which type of wearable blanket is right for you and your baby. 

1. Size

Rather than buying a different sleep sack for every month of life, wearable blankets usually work for more extended periods. You might see something like the following in the size options:

  • Small (0-6 Months)
  • Medium (6 – 12 Months)
  • Large (12 months to 3T)

These sizes aren’t set in stone, though. Every brand will have different guidelines. Make sure to pay attention to any sizing guides and choose the product that best fits your baby’s age and weight.

2. Fabric

Sleeper sacks are available in many different fabrics, from bamboo cotton to cotton muslin. There are pros and cons to each. 

Here’s a little more information on the most common options to help you decide:

  • Fleece: If you live in colder climates, purchasing a fleece sleep sack could be an excellent option for your baby. Just be careful that your baby doesn’t start overheating since this is a heavier textile.
  • Bamboo Cotton: Soft bamboo materials are not only one of the most eco-friendly options on the market, but they’re also luxurious, absorbent, and gentle on sensitive skin. However, one con is that some products tend to wrinkle after being washed.
  • Muslin: One of my favorite things about cotton muslin sleep sacks and swaddles is the weight of the fabric. It’s not super heavy and ensures enough protection to keep your baby warm with a smaller risk of overheating. It’s also an extremely breathable fabric that decreases the likelihood of skin irritation.

3. Budget

When you start reading about the best baby sleep sacks in the section below, you’ll notice we feature products with a wide range of price points. An item doesn’t always have to cost a fortune to be good. 

The cost of sleep sacks for babies varies greatly. Take a look at your own budget for baby and decide how much you’re comfortable spending. 

4. Style

From zippers to shoulder snaps and short sleeves to long, there are many different styles of wearable blankets. Consider the weather where you live, your baby’s unique preferences, and your list of wants and needs while shopping for a sleeper sack.

Infant Sleep Sack Safety – Here’s What You Need to Know

No matter what type of new baby must-haves you’re looking to buy, there’s no denying most of us put safety at the top of our priority list. We’re always looking for the best products for our little ones while also questioning which items are safe.

Don’t worry if you’re confused about the overall safety of sleep sacks for babies—our team is here to answer some of the most common questions about these products.

1. Are They a Safe Sleeping Option in General?

First and foremost, let’s answer the most general of questions: is a sleep sack safe for your baby? 

The answer is a resounding yes!

A 2019 study found that baby sleep sacks are a much better option for bedtime than loose bedding. While swaddling is still a great option in the early days because it mimics the womb, as soon as your baby starts rolling, a transition to sleep sacks is the best next step. 

2. Is a Weighted Sleep Sack Safe?

Per updates to the 2022 AAP safe sleeping recommendations, experts no longer recommend using weighted products on or around babies. 

3. Can Babies Use Sleep Sacks When They Start Rolling?

Absolutely! Sleep sacks are an excellent option after swaddles because they’re safe for rolling babies. 

4. Will Your Baby Overheat in a Sleep Sack?

Overheating in sleep sacks is one of the only risk factors when using these products. It’s always crucial to pay close attention to your baby’s temperature while using wearable blankets. 

Keep tabs on how their skin feels and maintain a safe temperature inside their nursery (between 68 and 72 degrees.)

Since temperature control is crucial for newborns, you’ll also want to pay attention to the TOG rating of whichever sleep sack you’re interested in. 

TOG, or Thermal Overall Grade, represents the warmth measurement of various products and materials. The higher the TOG number is for a particular item, the warmer it will feel to baby. 

5. Are Wearable Blankets Good for Your Baby’s Hips?

Swaddling is a fantastic tool for new parents but doesn’t come without risks. One of which is hip dysplasia. When babies are improperly swaddled, it can interfere with the their hips. 

The same, however, can’t be said about sleep sacks. 

Since wearable blankets don’t wrap tightly around a little one’s body, their hips are less restricted.

When Should You Stop Using a Sleep Bag?

Discontinuing the use of a baby sleeping bag is less about age and more about size. While designers make large sleepers to fit toddlers, many little ones start to outgrow them around 2 years old.  

The good thing is that by the time your child is too big for their sleep sack, they’re typically the right age to start using a blanket
