Swaddelini grey swaddle in size small, new without tags condition. Details from site: World’s First and only 3D Knit Seamless Swaddle Help your baby sleep and control the moro-reflex that often wakes them up. Our Hug Technology® helps babies learn to soothe themselves back to sleep after experiencing moro-reflex and active sleep which our good for brain development! Most swaddles out there restrict movement but the swaddelini celebrates movement and gives babies the freedom to move and learn how to self soothe. This makes transitioning out so much easier! When baby can roll, leave arms out. Material This swaddelini is made with post-consumer recycled nylon, moisture-wicking nylon and elastic for the compression areas. 100% of all these yarns are manufactured here in the USA. Yarn technology is the last piece of the textile industry that we still have domestically and swaddelini takes full advantage of this valuable resource. Sizing Small: babies 6-12 pounds. If your baby is at 12 pounds but long and skinny, still get the small. If short and chunky and 12 pounds, the large should work.
