As a parent, you’re probably taking all the necessary precautions to make sure they grow up healthy. Did you know something as innocent as a stuffed animal in their crib puts your child at risk for suffocation?

Loose blankets and bumpers are also potential risk factors. Sudden Infant Death Syndrome, SIDS, is when a child under the age of one suddenly dies in their crib.

We compiled a list of the best sleep sacks for your baby. As you look over the list the benefits of sleep sacks will become clear. Your baby will sleep peacefully inside their sleep sack, which will allow you to sleep better as well. Your little mini me can count sheep and catch z’s safely.

Criteria Used to Evaluate The Best Baby Sleepsacks for Kids in 2018

By now you know the importance of sleep sacks. Seeing as how they are so important, and your baby will be using them often we took making this list seriously. Through our research we found sleep sacks that are safe, developmentally appropriate, and suitable for all babies.


Always our number one priority! As discussed earlier, overheating is a common cause of SIDS. We made sure to have a wide variety of sleeveless sleep sacks on this list. Sleeveless sacks will keep your baby’s body warm but also allow air to circulate through the arm holes to keep them from overheating.

If the sleep sack has sleeves, it is not recommended for your baby to wear long sleeves underneath it. Sleep Sacks also eliminate loose blankets in your child’s crib. Once your child is secure in the sleep sack they won’t be able to kick it off. This eliminates the possibility of them getting tangled in loose fabric and suffocating.

We recommend buying a sleep sack that is true to size as a snug fit will also eliminate excess fabric. Several of the sleep sacks have “Back is Best” sewn on the chest area. This serves as a great reminder to the parents, to put their baby on their back. When babies sleep on their stomach or side, they are at risk of suffocating. There are sleep sacks that are made of lightweight material for the warmer months and warmer climates.

Developmentally Appropriate

One of the great things about sleep slacks is that they don’t restrict your child’s movement. Unlike blankets that are wrapped tightly around your baby, sleep sacks give your child the ability to move their legs freely. Babies love to kick and it’s good for the development of their legs and hips. Sleep sacks also allow your baby to return to their natural sleeping position, which is with their arms near their head.


This is list is full of sleep sacks that appeal to both boys and girls. There are a variety of patterns, colors, and designs of sleep sacks displayed throughout this list. Most of the sacks listed carry several different options of sizes. Whether your baby is a newborn or a toddler, there is a sleep sack on this list that is perfect for them.


Frequently Asked Questions

Q: How many sleep sacks should I purchase for my child?

A: We recommend having at least 5, so you can be prepared for leaky diapers.

Q: What should my baby wear underneath the sleep sack?

A: This all depends on the temperature of your nursery. Typically a cotton onesie works great, if your sleep sack is sleeveless go for a long sleeved onesie.

Q: Can I purchase a size larger so my baby can use it as they grow into it?

A: We recommend purchasing the size that matches your baby’s current size. Excess material can bunch up around your baby’s nose or mouth and suffocate them.

Q: What type of sleep sack should I use in the Winter?

A: Sleep sacks that have a higher TOG, and are made of fabrics like fleece and sherpa are perfect for the winter months or cold climates.

Q: What is a TOG rating?

A: TOG refers to a unit of measurement for temperature control/thermal resistance.  It originates from an old slang word tog, which referred to clothing, and therefore is often used as a standard in the textile/fabric industry.  The scale starts at 1 Tog (meaning the item rated is suitable for winter conditions), and goes up to 15 Tog (meaning the item is best used during summer/in warmer climates).  The ideal temperature for your nursery sits between 68-72 degrees, so keep that in mind when looking at TOG ratings for items you’ll be using in your home vs. outdoors or traveling.

Q: Can my baby sleep under my comforter with me?

A: It is strongly recommended that you never allow your baby to sleep on a soft surface. Your baby should sleep in their crib, on their back.

Q: How many stuffed animals can be in my child’s crib?

A: None! Loose blankets, stuffed animals, pillows, and soft bumpers can all be risk factors for suffocation when left in your child’s crib.

Q: When can my child sleep with a blanket?

A: Small blankets become less hazardous to your child as they reach one.
