SwaddleDesigns Organic Transitional Swaddle Sack – Arms Up Half-Length Sleeves, Small (0-3 Months, 6-14 lbs)

Overview

The Organic Transitional Swaddle Sack is designed for a smooth sleep transition when your baby moves away from a traditional arm-restraining swaddle. It combines an arms-up design with half-length sleeves and foldover mitten cuffs to support self-soothing while keeping tiny arms close to the body for a secure, cozy feel.

With safety-minded details, this sleep sack uses a two-way zipper with a zipper guard for gentle diaper changes, and a design that allows arm mobility if your baby rolls onto the tummy. The fabric is 100% organic cotton and GOTS certified, offering breathable, soft comfort that helps your baby stay comfortable in moderate temperatures.
