Knirose Premium Soft Cotton Swaddle Sleep Sack – Arms Up Design, 2-Pack, 3-6 Months

Meet the Knirose Arms Up Swaddle Sleep Sack

Designed for peaceful nights and curious little movers, the Knirose Premium Soft Cotton Swaddle Sleep Sack features an Arms Up design that aligns with a newborn’s natural sleep posture—arms tucked near the head with room to move. While every baby is unique, this setup aims to provide a secure, breathable environment that respects your little one’s preferences and sleep rhythms. The fabric blend of 95% cotton and 5% elastane offers a soft, gentle touch with subtle stretch, creating a familiar, womb-like feel without constraining growth or movement.

In addition to comforting textures, the design considers common newborn behaviors. The Arms Up configuration supports a preferred position for many babies, giving space for tiny movements while keeping little arms safely near the head. The result is a snug yet breathable layer that adapts as your baby shifts through sleep cycles and learns new milestones.
