The Best Sleeper Sacs: Keep Baby Warm Safely

*This is a sponsored post on behalf of baby deedee. All opinions are my own.

What is a sleeper sac? A sleeper sac, also known as a wearable blanket, is the answer to keeping your baby snug and warm without the risk of suffocation that can be caused by loose blankets covering your baby’s face. It is like a tiny sleeping bag with arm holes that your infant wears. Wearable blankets are recommended by the CDC and American Academy of Pediatrics (AAP) to help create a safe sleep environment.

It is inevitable that you will spend a good amount of time folding and wrapping your baby’s swaddle blanket just right to see that your baby has broken free out of it. Or when your baby starts to roll over and swaddles are no longer safe…What do you do now?

Do you have to abandon blankets all together? Well…Not anymore! Baby deedee’s sleeper sacs are your answer! All sleeper sacs are not the same, let me explain why the 4 listed below are some of my favorites. 

“What does TOG mean on sleeper sacs?”

Before buying any sleeping sacks, you’re going to need to know what TOG means. There are many different types of wearable blankets out there and each one will probably have a TOG value listed. TOG stands for “Thermal Overall Grade”. It is a score that tells you how well the fabric keeps you warm depending on its thermal resistance. 

This means the higher the TOG value, the warmer the fabric. You will need to know the average temperature in the room your baby sleeps and match it with a TOG that is best for your baby’s sleeping environment. 

Dress your baby accordingly underneath. For example, if it is Summer and hot outside, you would most likely need to choose a lightweight sleeper sac with a low TOG and have your baby wear something lightweight underneath.

However, all babies are different and the estimated temperatures are just a guide. It is vital the parent makes sure the fabric and baby’s clothing underneath would not cause the baby to overheat. 

The 4 Best Sleeper Sacs for Baby 

Baby deedee’s sleeper sacs have a feature that stands out above all the other brands! That feature is the patented shoulder snaps. 

No more waking up your sleeping baby when you go to put them in their sleeping sack and feed their arms through the holes. Just snap-snap-zip! This may seem like a small difference but it is a game-changer when it comes to the ease of getting your baby in and out of sleeping sacks. 

Other great features for these sleeper sacs include:

-oversized custom zipper toggle to make zipping and unzipping super easy for tired parents during those late night diaper changes

-reverse zippers so baby can stay zipped in the top half of the sleeper sac while you change their diaper

-the material used for the sac sleepers is very soft

-comforting cocoon-like shape so your baby feels secure but also has enough room to kick and move around

My 3-year-old wears this one at night. He calls it his “whale tail”. Before using this sleeper sack, he kept waking up at night because he was kicking his blanket off and was cold. He knows he is not allowed to get out of his toddler bed without permission so we don’t worry about him getting up and tripping over it. The first night we used it, he slept the entire night without waking up because he was warm and cozy.

*Baby deedee makes their sleeping sacks rather long for ample room for your baby to move around and great for your child to use for a while as they continue to grow. 

However, pay close attention to the length when ordering your sleeping sack. My son is 3 months and 16 pounds so according to the weight recommendation, he could wear a size medium. But when placed in the size medium, the sac was too long and could potentially cover his face when he curls his feet up to his chest.

BUT, I switched out the size for a small which aligns with his age and also falls within the recommended weight suggestion. This size is perfect for him. I’ve seen other reviewers comment they needed to size down…SIMPLE fix…look at ALL the size suggestions including the lengths.

Sleeper Sac Frequently Asked Questions: 

“What is a sleeper sac?”

Sleeper sacs are basically a tiny sleeping bag that your baby wears. It has holes for your baby’s head and arms to go through and a zipper in the front. These wearable blankets keep your baby feeling safe, warm, and snug while they sleep. 

The sleeper sacs also give your baby plenty of room to move around and it does not restrict hip movement. This allows your baby to be able to kick and roll over as desired while wearing the blanket. 

“What is the purpose of sleeper sacks?”

The purpose of sleeper sacks is to keep your baby snug and warm without the risk of suffocation that can be caused by loose blankets. 

“How long should babies wear a sleeper sac?”

You should follow the age, height, and weight guidelines provided on the sleeper sack. Some sleeper sacks can be used up to age 5! If you are using a sleeper sac for mobile babies and toddlers that do NOT have foot holes, the sleeper sac should only be used within the crib. You do not want your child standing up and walking while wearing the sleeper sac because they could fall. 

“When should you stop using a sleeper sac?”

You should stop putting your baby in sleeper sacks when they have outgrown the age, height, and weight suggestion. It is also important to be mindful of when your baby starts to pull up, stand, and walk when wearing a sleeper sac. You do not want your baby tripping inside the sac and falling. 

“Are sleeper sacks safe?”

Sleeper sacs are made to replace loose blankets that are dangerous and a suffocation risk to babies. The sleeper sac needs to fit and be used correctly. The CDC actually recommends you use wearable blankets if you are worried about your infant being cold. 

“Can baby overheat in sleeper sac?”

A baby CAN overheat wearing a sleeper sac. It is important to choose a sleeping sack with an appropriate TOG for the room temperature and dress them accordingly underneath. Infant should not feel hot to the touch, especially when placing your hand on their chest. 

“Can babies suffocate in a sleeper sack?”

The sleeper sac should not be long enough that the bottom could cover your baby’s face when they raise their feet. Make sure you have the correct size on your child. A sleeper sac should not be used if your baby is able to unzip or unsnap the sleeper sac on their own. The sleeper sac should also not be used if your baby’s head can pass through the neck hole when it is being used. 

“Should a baby wear a onesie under a sleeper sac?”

A baby can wear a onesie underneath a sleeper sac. You could also dress your baby in just their diaper or in their regular sleepwear. Take in consideration the temperature of your child’s room and the TOG on the sleep sac. 

“Do you put a sleeper under a sleep sac?”

You can put a sleeper on your child underneath a sleep sac. Most sleep sacs say they are to be used over your child’s regular sleepwear. However, all babies are different so it is important to check your child to see if they feel hot or cold to the touch. It is important to keep your child’s room at a temperature comfortable for a lightly clothed adult. To avoid overheating, do not over bundle your infant.
