## Overview

The SwaddleDesigns Transitional Swaddle Sack is a patented, nurse-designed swaddle solution for babies 0-3 months (6-14 lbs) that promotes safer, better sleep by allowing arms-up self-soothing and partial startle reflex suppression. Featuring half-length sleeves with foldover mitten cuffs and a convenient 2-way zipper, it supports natural flexed positioning and easy diaper changes, making it the ideal next step from traditional swaddling.

## Description

The Transitional Swaddle Sack is the easiest & safest way to wean 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. Importantly, the patented design is safer because baby can use their arms if baby rolls over during 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. US patent, D833,613 with patents in EU, UK, China, Japan, Korea.

Review: Exactly like picture but not so helpful - I would suggest a swaddle me swaddle or swaddle blanket instead as baby didn't like arms being open because of moro reflex
Review: Came wrong size and used - 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)

### ⭐⭐⭐⭐⭐ Review
*by B***A on 9 July 2021*

My baby HATED being swaddled since she was about 3 weeks old. She always wanted her arms out, but would startle herself awake. Cue this amazing discovery! Worked like a charm from night one. The material is soft, double zipper makes diaper changes a breeze. The arms are not so short and constricting that she can't move her arms like some swaddled sacks. It's perfect because sometimes her wants to stretch or put her hand to her mouth, but we're still in the foldover mitten stage. The neck hole is not too tight at all for her, we're still in 0-3 and she's 11 lbs. All in all a great purchase for restless nights!
