Amazing Baby Swaddle Set includes our most-loved Transitional Swaddle Sack and a set of 4 coordinating cotton muslin Swaddle Blankets. The Transitional Swaddle Sack is ideal for babies who prefer to sleep with arms up and babies who are starting to rollover. The uniquely-shaped, ½-length sleeves are not full length, so when mitten cuffs are closed, baby's arms will be flexed close to body for swaddle snugness. The foldover mitten cuffs may be worn open or closed. Helpful 2-way zipper with 2 zipper pulls. The zipper zips down from the neck to make it easy to place baby in the sack and zips up from the feet to make it easy to change baby's diaper. Our soft and breathable, openweave cotton muslin swaddles are an every day baby essential. Each blanket in set of 4 measures 46 x 46 inches (116 x 116 cm). The generous size and our helpful labels make swaddling easy as 123. Beyond swaddling, use when feeding baby, as a sunshield, playmat for tummy time, over the stroller, and more. The cotton muslin is pre-washed to increase softness and we use premium cotton yarns to increase durability and minimize pilling. Coordinates with a variety of our quality baby essentials. Machine wash warm, tumble dry low.
