## Overview

The SwaddleDesigns Transitional Swaddle Sack is a nurse-designed, 100% cotton sleep solution featuring half-length arms-up sleeves with foldover mitten cuffs to partially suppress the Moro reflex while allowing safe movement. Its patented 2-way zipper simplifies diaper changes, and the 0.5 TOG breathable fabric ensures comfort. Ideal for babies transitioning from traditional swaddles, it supports safer sleep for rolling infants and promotes self-soothing, making it a top-rated, gradual transition swaddle trusted by thousands of parents.

## Description

The Transitional Swaddle Sack is the easiest & safest way to transition baby from a traditional swaddle. The arms up sleeve design allows baby to self-soothe and the unique ½-length sleeves with foldover mitten cuffs closed provide partial suppression of the Startle Reflex to promote better sleep; and, if baby rolls over during sleep, the sleeves allow baby to use arms to lift torso and head to access air to promote safer sleep. The Transitional Swaddle Sack is ideal for babies who prefer to sleep with arms up, babies who are starting to rollover, and babies who break out of a traditional swaddle. The uniquely-shaped, ½-length sleeves are not full length, so when mitten cuffs are closed, baby’s arms will be flexed close to body for swaddle snugness. The foldover mitten cuffs may be worn open or closed. Caregiver can open one or both cuffs, so baby can self-soothe by sucking directly on hand. Helpful 2-way zipper with 2 zipper pulls. The zipper zips down from the top to make it easy to place baby in the sack and zips up from the bottom to make it easy to change baby’s diaper. Designed by a nurse. 100% Cotton. Soft, stretchy cotton knit. 0.5 TOG. Machine wash warm and tumble dry low. US patents 11,812,795 & D833,613 with patents in EU, UK, CA, CN, JP and other countries.

Review: Great quality, wonderful transition, so affordable - Recommended by a friend when I wasnt finding anything that could work as a transitional swaddle once baby started rolling. This did the trick! Easy to use, quality material, great price point (so nice because you don't use these sorts of things for very long). Love the color options as well; got multiple since they are so affordable. Fit great and she slept great in them.
Review: ⭐⭐⭐⭐⭐ A total game changer for our baby! - ⭐⭐⭐⭐⭐ A total game changer for our baby! This sleep sack deserves 100 stars and it’s so cheap compared to the counterparts!!!!!!! I almost never write reviews, but I had to for this sleep sack. Our baby has always been a very active sleeper and constantly wakes himself up by flailing his arms. We tried several different sleep sacks, and nothing made a noticeable difference. This is only our second night using this one, and the results have honestly amazed us. Tonight I laid him down awake, and within 3 seconds he was asleep! I watched him on the baby monitor because I couldn’t believe it. He looked so comfortable and settled immediately. The fabric is incredibly soft, lightweight, and breathable, and it seems to provide just the right amount of comfort without restricting movement. It has already become an essential part of our bedtime routine. I was so impressed after the very first night that I already bought a second one so we’ll always have one while the other is in the wash. If your baby struggles with settling down or constantly wakes themselves up with active arms, I absolutely recommend giving this sleep sack a try. So far, it’s been one of the best baby purchases we’ve made! ❤️👶

### ⭐⭐⭐⭐⭐ A Transition Swaddle You Can Use Even After Baby Starts Rolling
*by R***R on July 27, 2026*

We loved the Love to Dream swaddle until our little guy started rolling. Once we had to unzip the arms, he was constantly startling himself awake and waking much more often. This sleep sack was exactly what we needed. His arms are still somewhat contained, which helped reduce the startle reflex, but I also love that the mittens can be opened later as your baby becomes more comfortable rolling. It made the transition much smoother than going straight to a regular sleep sack. Another feature I really like is the roomy bottom. It gives plenty of space for kicking and healthy hip movement while still keeping him cozy. If your baby is outgrowing a swaddle but isn’t quite ready for completely free arms, I highly recommend giving this one a try.
