SwaddleDesigns Organic Transitional Swaddle Sack – Arms Up Sleeves, 6-9 Months, Watercolor Peach Blush Poppies

The Organic Transitional Swaddle Sack helps babies ease into a gentle transition from traditional arm-restraining swaddles. Crafted from 100% organic cotton with a breathable 0.5 tog, this sleep sack offers a soft, cozy layer for moderate warmth and comfortable movement.

Why choose a transitional swaddle?

This design is purpose-built for babies who prefer arms up, are starting to roll, or like to self-soothe by touching their hands. The sack positions the arms in a natural, flexed posture while still allowing mobility if baby shifts positions, which can help air can flow and reduce the chance of overheating during sleep.

• Arms-up sleeve design with half-length sleeves and foldover mitten cuffs (open or closed) supports self-soothing and provides gentle control of startle reflex.
• Two-way double-pull zipper with a zipper guard offers easy diaper changes and protects baby's skin from rough edges.
• 100% Organic Cotton, GOTS certified, with a soft, breathable feel and a light 0.5 tog warmth for moderate temperatures.
