## Overview

The SwaddleDesigns Transitional Swaddle Sack is a nurse-designed, 100% cotton sleep solution featuring arms-up half-length sleeves with foldover mitten cuffs to partially suppress the Moro reflex while allowing safe arm mobility. Its patented 2-way double-pull zipper enables quick diaper changes, and the design supports healthy hip development. Ideal for babies 0-9 months transitioning from traditional swaddling, it promotes better, safer sleep with breathable, lightweight fabric and adjustable mittens for gradual transition.

## 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: ⭐⭐⭐⭐⭐ 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! ❤️👶
Review: A Transition Swaddle You Can Use Even After Baby Starts Rolling - 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.

## Features

- TRANSITIONAL SWADDLE SACK promotes BETTER SLEEP and SAFER SLEEP. Perfect for babies starting to or able to ROLL OVER, babies who like to sleep with ARMS UP and suck on hands to SELF-SOOTHE, and babies who can escape or get out of a classic swaddle
- LITTLE SLEEVES with BIG PURPOSE. ARMS UP 1/2-LENGTH Sleeves with mitten cuffs closed provide arm mobility and partial suppression of Moro Reflex, so BABY SLEEPS BETTER, and if baby rolls over, allow baby to use arms and reposition, so BABY SLEEPS SAFER
- MOST GRADUAL TRANSITION with NO COLD TURKEY. With mitts closed, TSS may be used to partially suppress Moro reflex for multiple weeks when baby is able to roll and still has Moro reflex. After the reflex fades, parents may gradually open one mitt at a time
- Recognized by IHDI as hip friendly. Elbow-length sleeves support baby’s arms in flexed position and allow arm mobility. Not a tight swaddle nor a loose sleeveless wearable blanket. Lower section supports baby in a flexed position to help baby feel secure
- DESIGNED BY A NURSE with Baby's Best Interest in Mind. FOLDOVER MITTEN CUFFS may be worn OPEN OR CLOSED. Caregiver can open one or both mitts, so baby can SELF-SOOTHE, or close the mitts to AVOID THE RISK OF FACIAL SCRATCHES
- 100% Cotton. TOG 0.5 Soft stretchy fabric. 2-way double-pull zipper for EASY DIAPER CHANGES. Use baby's weight to select size: S 6-14 lbs 0-3 mo; M 14-21 lbs 3-6 mo; L 21-24 lbs 6-9 mo. Machine wash. Tumble dry. US Patent 11,812,795 WW patents online

### ⭐⭐⭐⭐⭐ The best sleep sacks!
*by B***A on June 26, 2026*

These swaddles are such a great affordable option! My daughter absolutely loves her arms being up. After having the more expensive versions, I was looking for an alternative and this is it! Works great and fits so nicely. Super stretchy for her kicking legs and is soft to touch. My daughter calms when I put these on for her. So easy to use and easy to clean. The colors are so pretty as well. It’s not too thick but has a little layer so a great option for hot sleepers like my baby. It has held up great and is awesome for babies who might be learning to roll. She is still able to use her arms and move them around while lifting her head when it happened
