The Transitional Swaddle Sack is designed to help babies transition from a traditional swaddle to a more independent sleep. It features arms up half-length sleeves and foldover mitten cuffs that can be worn open or closed, allowing the baby to self-soothe or be protected from facial scratches. The snug fit around the tummy and shorter sack support the baby's legs in a flexed position, promoting better sleep. The 2-way zipper makes diaper changes easy, and the soft, stretchy cotton knit ensures comfort. Ideal for babies who prefer to sleep with arms up, are starting to roll over, or break out of traditional swaddles.
