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!"

Half-Up Sleeves Sack

Our 10 week old daughter started to break out of her Halo swaddle and sleep with her arms up by her ears. She still has strong Moro reflex so it was clear she couldn’t move right into a sleep sack. I ordered a few different brands online and am very happy with the Half-Up Sleeves Sack. It’s soft, warm but ideal for nighttime with a pj onesie underneath, and allows her to sleep in her desired position while tempering her reflex. I like that the arms are semi flexible though as it allows her to move around more naturally. It’s been a great transition product for us.

Thank you for your glowing review! I’m so happy to hear our Half-Up Sleeves are working so well for your sweet baby.


I bought this because my so. Kept breaking out of his swaddle AND likes to suck his thumb. I still needed him to be able to sleep, but keep him from putting his fingers in his mouth. This did the trick. It’s a great sleep sack! I’d love to get the warmer one for winter!

Great investment!

I was really nervous about transitioning out of the swaddle with arms down but found this and it’s helped so much! My little is doing great in it and love that it also follows all the safety guidelines for sleep. Definitely recommend

Sleep sack with sleeves

We are using the sleep sack with sleeves option to help our 4 month old get ready to move out of her Merlin suit. Going great for naps so far, really nice material and easy zipper from bottom to top. Definitely a fan of this being a mom of two and would reccomend
