## Overview

The SwaddleDesigns Transitional Swaddle Sack is a patented, nurse-designed wearable blanket for 3-6 month olds (14-21 lbs) that combines half-length arms-up sleeves with foldover mitten cuffs to promote safer, longer sleep by partially suppressing the startle reflex while allowing self-soothing. Made from breathable 100% cotton knit with a 0.7 TOG rating, it features a convenient 2-way zipper for easy diaper changes and supports healthy hip positioning, making it the perfect next step from traditional swaddling.

## 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. 0.7 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: So good, I ordered another one! - The Transitional Swaddle Sack has been a game changer for our baby’s sleep routine. The material has the perfect amount of stretchiness, giving our little one enough movement while still providing that snug, comforting feel. Since using it, our infant has been sleeping almost through the entire night, and the improvement in sleep quality has been amazing. The zipper quality is excellent,smooth, durable, and makes nighttime diaper changes quick and hassle-free. It’s incredibly easy to use, even when you’re half-asleep during late-night changes. The fabric is breathable, keeping our baby comfortable without overheating, and soft enough to feel gentle on their skin. Overall, this swaddle sack offers the perfect mix of comfort, flexibility, and convenience. Highly recommended for any parent looking to transition their baby safely and comfortably!
Review: Best sleep sack - Love these sleepers so much I went back for more. I love that we can free up a hand so my baby can self soothe. The material is thick and soft, easy to clean. The zippers are well made. I will say the ‘“mittens” to close off the arms do tend to stretch easy, so whether or not I leave my baby’s hand out, he always wakes up with both arms out anyways lol. I like the fit, it’s nice and snug, giving my baby comfort while he sleeps but also long enough to ensure there’s plenty of leg room. 10/10 will continue to use and buy

Hands down the best! We tried so many brands with our baby and these were an instant favorite. They’re so soft and great quality! They’re breathable but warm and roomy! I love the option to allow his hands to be covered or out. We have 3 and will buy more!
