The Transitional Swaddle Sack is designed to help babies transition from a traditional swaddle to a wearable blanket. It features arms up half-length sleeves and foldover mitten cuffs that can be worn open or closed. The snug fit helps babies feel secure while allowing them to self-soothe and move their arms for safer sleep. The sack is made from soft cotton knit and includes a helpful 2-way zipper for easy diaper changes. Ideal for babies who prefer to sleep with arms up, are starting to roll over, or can break out of a traditional swaddle.
