## Overview

The SwaddleDesigns Transitional Swaddle Sack Medium (3-6 months) is a patented, nurse-designed wearable swaddle made from soft, breathable 100% cotton. Featuring half-length sleeves with foldover mitten cuffs, it promotes safer, longer sleep by partially suppressing the startle reflex while allowing babies to self-soothe and roll over safely. The snug, hip-healthy fit supports natural positioning, and the 2-way zipper enables quick diaper changes. Ideal for babies transitioning from traditional swaddles weighing 14-21 lbs.

## 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.

## Customer Reviews

### ⭐⭐⭐ Exactly like picture but not so helpful
*by A***R on 25 September 2021*

I would suggest a swaddle me swaddle or swaddle blanket instead as baby didn't like arms being open because of moro reflex

### ⭐ Came wrong size and used
*by L***Y on 18 December 2022*

I think someone bought a bigger size and returned a used old smaller sized one. Company then sent that one to me without checking the returned item. I bought a medium but a small was inside the medium packaging and it was dirty and used (all bobbly)
