The Transitional Swaddle Sack is designed to help babies transition from traditional swaddling. It features a unique arms-up design that allows babies to self-soothe while promoting better and safer sleep. The half-length sleeves with foldover mitten cuffs provide partial suppression of the startle reflex, making it ideal for babies who prefer to sleep with their arms up or are starting to roll over. The snug fit around the tummy and shorter sack support the legs in a flexed position, helping babies feel secure. The 2-way zipper allows for easy diaper changes, and the fabric is made from 100% cotton for comfort. This product is suitable for babies weighing between 6-14 lbs and aged 0-3 months.
