Swaddle Sleeves Sack™ & Mitten Sleeves Set


Fantastic transitional product!

"As a baby sleep expert, neonatal nurse, and mom of 4, I recommend Swaddle Sleeves as a fantastic transitional product for babies."

-Cara, Taking Cara Babies

Highly recommend!

“As a pediatrician and a mother of two boys who had sleep issues, I highly recommend this product. [It] is wonderful to help with that transition and prevent awakening from normal reflexes. Swaddle Sleeves will help give everyone a good night's sleep!”

-Navneet Brar, Pediatric Emergency Medicine MD

Awesome product!

"My son started sleeping 6+ hours every night as soon as I started using these on him at 4 weeks old and that soon encouraged him to start sleeping 11+ hours!! They just kept him for doing the jerk reflex babies do. Awesome product I truly believe in!"

-Chelsea S., Customer

How do Swaddle Sleeves work?

By using a strategic layering technique in our sleeves, we have created the same effect of dampening babies’ startles as they transition out of the swaddle that you’re used to with our products, but WITHOUT adding ANY weighting or restrictive design. The dampening effect is created through the air pockets in our inner polyfill layer. Similar to what’s found inside a higher TOG wearable blanket, our padded Swaddle Sleeves do not restrict movement, but do provide just an extra bit of reassurance to your little one as they transition out of the swaddle. Another way to understand our proprietary layering method would be to imagine the padded Swaddle Sleeves as being made of the same material of a wearable blanket with a higher TOG (thermal overall grade) rating, whereas our Mitten Sleeves would be classified as having a lower TOG rating, but without any added restriction in sewing or design. Sleep safety will always, always be #1 at Two Baby Bears and Co.

Are all of the sleeves interchangeable?

Yes, all of our sleeves are interchangeable. For example, let’s say you purchase the Swaddle Sleeves Sack. With it, you get 2 sets of sleeves, our Swaddle Sleeves and Mitten Sleeves. You can use either one (most parents prefer to start off with our Swaddle Sleeves and then transition over to the Mitten Sleeves!), or you can also purchase our Add-On Star Sleeves, for example, if for some reason your sweet baby isn’t taking to the Swaddle Sleeves, without having to purchase a whole new product! As we grow, we’ll be offering bundle options for our sleeves, but currently, we only have our Add-On Sleeves as a purchase option so you can mix and match without having to buy a whole new product!

Are these products safe for sleep?

Our products have been designed according to the AAP’s (American Academy of Pediatrics) guidelines for safe sleep. Not only have we undergone certified third-party laboratory testing and surpassed the Consumer Product Safety Commission’s safety standards, we also partnered with pediatric physical therapists, pediatric nurses, and pediatricians throughout our development and design process to ensure that you and your baby are getting the safest, most effective swaddle product possible. Our products have been approved by global-wide safety standards and verified through Intertek and SGS Testing, both of which are world-leading inspection, verification, testing, and certification company.

At Two Baby Bears and Co., you can rest assured that we will always put safety first, as evidenced by the immediate disposal of our weighted inventory (at a huge financial loss to the company’s detriment) as soon as the updated AAP safe sleep guidelines were released in June 2022. We believe that transparency matters, and our relationship with our parents and customers is of utmost importance to us.

Why are all of the sleeves zippered and removable?

Because as parents ourselves, we know how difficult it is to buy a product and have it just not work for your baby, and then be stuck with it! That is why we provide two different sets of sleeves with our Swaddle Sleeves products and also give you the option of removing the sleeves entirely so that 1) in case the product doesn’t work out for your baby, you can still use it as a standard sleep sack/bodysuit/pajamas, and 2) to give you and your baby multiple options of how to use our product in case your baby doesn’t like it one way. This is also why we sell our “Add-on Sleeves,” and 3) for longevity of use! It’s no fun when you can only use a product for a set amount of time and once that time is over, throw it in the dresser drawer never to be seen again. We want you to get the most use out of our products and be able to use them long after you’re done with the swaddle transitioning stage! 

How do I know which product is right for my baby?

We wanted to make sure that our products were not only safe and functional, but also practical and easy to use for parents. Take our Product Quiz to find the perfect product for your baby!

Are sleep sacks with sleeves safe?

As long as the infant is dressed appropriately for the temperature, swaddles and sleep sacks with sleeves are perfectly safe. Since your baby can't exactly tell you how they feel, it's up to you as a parent to find the right room temperature and use your judgment with help from the AAP's guidelines for a safe and comfortable room temperature. The recommended temperature for babies is between 68 to 72 degrees Fahrenheit or 20 to 22 degrees Celsius. Experts recommend to check the back of baby's neck to see if your little one is warm instead of their hands or feet for a more accurate reading. Another helpful measure for temperature is to dress baby in just one more layer than what you are comfortable wearing. Finally, many of our sleeves come with an optional mitten cuff, so you have the option to leave the hands open or covered depending on your little one's comfort!

Second purchase!

After transitioning almost 2 months ago, this sleep sack remains part of our sleep routine. And it's stayed in fantastic condition! Such a great product - I recommend this to all the moms I know.

We love it!

Such a great purchase! Our little guy was on the verge or rolling and this is the perfect transition!! He’s so cozy and sleeps all night long!

Worth it!!

I rarely leave reviews, but I had to for Swaddles Sleeves! I was so nervous to transition our baby out of the swaddle when she started to show signs of rolling. We tried Merlin and Zipadee Zip, but the Merlin didn’t fit her well since she’s a bit lengthy and the Zipadee Zip didn’t help with her startle reflex. I came across Swaddle Sleeves and wanted to give it a try. She slept 12 hours the first night in it and now naps 1-2 hours! I also love that we can try and use different sleeves as she continues to grow and develop. Definitely worth it.

Absolutely obsessed with this product. My 3 month old loved being swaddled but started showing signs of rolling. I was terrified to transfer her out of the swaddle but I saw this product through TakingCaraBabies and thought I would try it. My baby loves it’s and is now sleeping 9-10 hours through the night. It also brings me peace of mind that she has mobility if needed. I will be recommending to all my new mom friends!

Worked Beautifully!!!

This sleeper has worked so beautifully for my son. I needed to transition him out of his swaddle but still needed something to help muffle his reflexes and this did just that. Plus I love that it’s lightweight and I don’t need to worry about him overheating and it doesn’t prohibit movement. Highly recommend!!!

We thought we’d never see the day!

Seriously. Our little one would NOT sleep without a swaddle. We had to transition to a sleep suit which didn’t work well at all. As soon as we tried these puffy arms, everything changed. Baby is sleeping through the night and unswaddled!!!! Highly recommend if the sleep suits don’t work for your little!!!

Perfect transition

I’m so happy to have a product bridging the transition from swaddle to sleep sack. It’s soft and adorable and I sort of wish they had adult sizes. It’s especially nice to know it’s “roll safe”. Expensive but worth it.

Sharon W

I’ve used this for about 3 weeks and it has helped my baby with her startle reflex while falling asleep! The puffy sleeves and sleep sack are not too warm, and baby sleeps very comfortably. We are trying to use the sleep sack without the puffy sleeves now to see if it helped her graduate out of them. Very happy with my purchase! Everyone transitioning their baby out of their arms in swaddles should get at least one of these!

Swaddle Sleeves Sack & Mitten Sleeves Set

We got this for my daughter to transition out of from her Ollie. We transitioned 4 days ago and she’s honestly done really well! I wanted to use the swaddle sleeves but since it’s summer and she runs so hot, I had to use the mitten sleeves. They’re a bit too big for her but she’s sleeping just fine with them on! I ordered the Star Sleeves Sack as well so that we could have the Star Sleeves as an alternative option. For reference, my daughter is just one week shy of 3 months old.

Victoria L

Our 3 month old starting breaking free from traditional swaddles and also started showing signs of rolling. I heard of this product from Taking Cara Babies and I’m so happy for the recommendation! I love how it came with different sleeve options - we are still using swaddle sleeves which really calms his startle reflex. And he can soothe himself back to sleep most of the time without me going in. You can also tell how quality the material is, and that it’ll last a long time. Love it!
