The Omni Swaddle Sack is the newest innovation in swaddling and is already the recipient of many awards. The Omni makes it very easy for new parents to swaddle their newborn, and it allows for a variety of arm positions for swaddling safely. The Small Omni Swaddle Sack fits babies 6-14 lbs, 0-3m; and the 3M fits 12-18 lbs. The adjustable wrap is narrow and does not interfere with baby's hips, and the soft hook-and-loop fasteners make it easy to swaddle baby. The 2-way zipper allows parents to unzip from the foot to change baby's diaper without unwrapping the swaddle. The 2-way zipper makes it easy to place baby in the sack by unzipping from the top. The uniquely shaped 1/2 length sleeves have foldover mitten cuffs that may be worn open or closed. Parents can open one or both cuffs, so baby can self-soothe by sucking on hand or close the cuffs to protect from facial scratches. Super soft, 100% GOTS certified organic cotton knit is breathable, stretchy, and natural. Patented.
