## Overview

The Transitional Swaddle Sack is a nurse-designed, 100% cotton swaddle with half-length sleeves and foldover mitten cuffs that promote safer, longer sleep by partially suppressing the Moro reflex while allowing arm mobility. Featuring a patented 2-way zipper for easy diaper changes and breathable, stretchy fabric, it supports babies transitioning from traditional swaddling to independent sleep, ideal for newborns starting to roll over and self-soothe.

## 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: 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: Perfect sleeper - It’s soooo much longer than the size below, it’s a little comical 😂 but I’m not worried about him outgrowing it for a while so that’s great! Comfortable and soft. I love it.

### ⭐⭐⭐⭐⭐ Perfect Swaddle Transition
*by H***S on May 31, 2026*

This transitional swaddle sack is soft, well-made, and a great option for babies moving out of traditional swaddles. The arms-up design helps babies self-soothe while still feeling secure, and the mitten cuffs are a nice bonus. The watercolor mountains and trees print is absolutely adorable. A great sleep solution for little ones during the transition stage!
