In hindsight, I took my oldest out of a sleep sack far too soon.

What is a sleep sack?

Think a sleeping bag for babies.

Also called wearable blankets or sleep bags, sleep sacks are adorable little sleeping bags for babies and toddlers that are designed to keep them warm while they sleep.

A traditional sleep sack is a zippered (or snapped) sack that goes around your baby’s body on top of their pajamas.

Their head is always out of of the sleep sack. Some sleep sacks offer an arms-in option. Others have sleeves and leg holes.

According to the American Academy of Pediatrics (AAP), they are a much safer alternative to blankets when it comes to ensuring your toddler is safe as they sleep and reduce the risk of SIDS (sudden infant death syndrome).

If you have been thinking about getting your toddler a sleep sack, you probably already know just how much variety is available in the market today.

There are footed ones, newborn-friendly ones, ones made using wool, fleece, or cotton, and more. The list is endless. 

Unfortunately, having so many options to choose from often results in choice paralysis for many parents.

If this is the dilemma you have been dealing with, you have come to the right place! Here is a look at some of the best toddler sleep sacks on the market now! 

Why use a sleep sack for toddlers? 

Sleep sacks are a helpful tool for many parents.

They offer a safe way to put little ones to bed while sticking to the American Academy of Pediatrics’s safe sleep guidelines without blankets. They will keep your toddler warm at night without the need for loose blankets. 

Sleep sacks help ensure a smooth transition from swaddling in younger babies. You can keep using them right into toddlerhood to provide a safe sleeping environment for your child.

Keep using them until your toddler becomes too big for their sleep sack, which would mean it is time to transition to a big kid’s blanket. 

Are sleep sacks safe for toddlers? 

Yes, sleep sacks are completely safe for toddlers!

As long as the sleep sack fits your little one correctly, they can keep using it for as long as they want. You’ll want to check the size guide of the brand you purcahse to make sure you are getting the right size.

Kids love the security that comes with wearing a sleep sack. That’s why developmentally speaking, they will never quite age out of wearing them.

For this reason, you can keep using sleep sacks for as long as you can find ones that fit your child. Once your babe becomes too big for their favorite sleep sack, you can then transition to a regular blanket. 

If you are considering transitioning from sleep sacks, be sure to consult the AAP’s safe sleep guidelines and ensure that you keep all bedding and blankets out of the crib until your child is at least 12 months old. 

A sleep sack is a great way to bridge the gap after their first birthday until they can use a blanket in their crib.

At the end of the day, there really is no rush to stop using sleep sacks if your little one is not ready. In fact, you can upgrade to larger sizes now that more and more brands are making extra-large sleep sacks. 

Here are a few more reasons why sleep sacks are great for toddlers: 

  • An extra layer of warmth: When toddlers first start using blankets, they tend to kick them off in the middle of the night. Sleep sacks take care of this problem by staying put all night and guaranteeing that your little one will always be covered no matter how much she kicks!
  • They feel secure enough to sleep longer: Because sleep sacks keep toddlers covered all night, it makes them more likely to stay asleep for longer. If you have been trying to figure out how to make your kiddo sleep through the night, a sleep sack might just do the trick. 
  • Helps prevent them from climbing out of the crib: Has your little one started becoming more and more adventurous by the day? Has she started experimenting with climbing out of the crib on their own? Well, a sleep sack will prevent this by ensuring your toddler stays in the crib all night. Their legs will be enclosed throughout the night, which makes it harder to climb up over the side of the crib. 
  • A comforting part of the bed time routine: Sleep sacks can also help reinforce your toddler’s bedtime routine. When your kiddo puts it on, it acts as a cue that it is time to sleep. The result? You’ll have fewer bedtime tantrums to deal with!  

What to know about sleep sacks:

Before you buy a sleep sack, here are some of the most important things to consider: 

TOG levels

TOG stands for thermal overall grade.

TOG is a measurement standard that is used to determine season-appropriate sleep sacks. It defines the thickness and the amount of warmth that the sleep sack offers your child as she wears it.

Depending on the season, you will need different weights to ensure your toddler is comfortable at night and early in the morning. 

The lower the TOG level, the thinner the fabric. Lower TOG levels are used in warmer weather whereas higher TOG levels are used in cooler weather.

You pick your TOG level based on your child’s room temperature.


Next up is the type of material used. Consider going for organic cotton or bamboo viscose whenever possible as these materials are more sustainable.

Also, ensure that you get it in the correct weight to prevent your little one from sweating at night. If she sweats, adjust the clothing she has on underneath or get it in a lighter weight. 


To ensure your sleep sack is made with quality materials, confirm that the brand has the relevant industry certifications.

For example, the OKEO-TEX certification confirms that the sleep sack has been tested for 100 harmful substances, including lead, nickel, and phthalates, guaranteeing that the sleep sack is completely non-toxic and baby-safe. 

You also want to look for GOTS certified cotton when cotton is being used as a material.


I love zippers that start at the top and go to the bottom to close because they make it harder for toddlers to open them up themselves in the middle of the night.

Once your toddler can unzip their sleep sack and take it off, it becomes a tripping hazard and even a suffocation risk.

That said, sleep sacks come with lots of different types of closures, including zippers, sleeves, snaps, and more.

I do not personally like snaps because when you have a toddler and she stands while in the sleep sack, the poppers will easily snap open, releasing them. This can also be a potential crib risk because of the loose fabric. 

Keep in mind that ones that zip up from the bottom make for easy diaper changes.

Hands in or hands out

You also have the option of getting a sleeveless or sleeved sleep sack.

Some versions are also completely without sleeves and are designed to lock the hands in, although I would not recommend these for toddlers. 

I like using a sleeveless sleep sack with a long-sleeved pajama top.

This creates the right balance of warmth and comfort. It also gives my toddler some autonomy over his comfort, because most toddlers prefer their hands out at this age. 

Putting your baby to sleep in long sleeves helps keep them warm at night.
