Featuring unique arms-up half-length sleeves with foldover mitten cuffs, it gently suppresses the startle reflex while allowing safe movement for babies transitioning from traditional swaddling. Its breathable, stretchy fabric and innovative 2-way zipper make nighttime diaper changes effortless. Recognized as hip-healthy by IHDI, this medium-sized swaddle fits babies 14-21 lbs (3-6 months), promoting safer, longer, and more comfortable sleep. ## Description The Transitional Swaddle Sack is the easiest & safest way to wean baby from a traditional swaddle. The arms up sleeve design allows baby to self-soothe and the unique ½-length sleeves with foldover mitten cuffs closed provide partial suppression of the Startle Reflex to promote better sleep. Importantly, the patented design is safer because baby can use their arms if baby rolls over during sleep. The Transitional Swaddle Sack is ideal for babies who prefer to sleep with arms up, babies who are starting to rollover, and babies who break out of a traditional swaddle. 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. Caregiver can open one or both cuffs, so baby can self-soothe by sucking directly on hand. Helpful 2-way zipper with 2 zipper pulls. The zipper zips down from the top to make it easy to place baby in the sack and zips up from the bottom to make it easy to change baby’s diaper. Designed by a nurse. US patent, D833,613 with patents in EU, UK, China, Japan, Korea. Review: The Transitional Swaddle Sack has been a game changer for our baby’s sleep routine. The material has the perfect amount of stretchiness, giving our little one enough movement while still providing that snug, comforting feel. Since using it, our infant has been sleeping almost through the entire night, and the improvement in sleep quality has been amazing. The zipper quality is excellent,smooth, durable, and makes nighttime diaper changes quick and hassle-free. It’s incredibly easy to use, even when you’re half-asleep during late-night changes. The fabric is breathable, keeping our baby comfortable without overheating, and soft enough to feel gentle on their skin. Overall, this swaddle sack offers the perfect mix of comfort, flexibility, and convenience. Highly recommended for any parent looking to transition their baby safely and comfortably! Review: I’m not one to write reviews, never have actually so this is my first one but after a couples months of use I just had to leave my thoughts for those on the fence. My baby was very heavily reliant on swaddling to be able to sleep and had a really aggressive startle reflex so when trying to take it away it was a total nightmare. I decided to give this one a try after failing over and over to get him to sleep without a swaddle. I’m so glad I did cause he loves this transitional swaddle! Been about 3 months of using it and I’ve gotten him back in his own sleep space and taking naps independently again and having longer stretches of sleep (on days/nights I don’t use it cause it’s dirty he doesn’t sleep as long and wakes himself up all night). It’s contoured enough to feel “snug” but still has plenty of leg room and can still put his arms down but helps lessen the arm flailing a lot. Love the double zipper feature and it’s very soft and just thick enough to keep him warm but not overheat. I highly recommend this product for the parents out there struggling to transition out of a traditional swaddle. I got the green one for reference, I read other reviews that said different colors seem to have different fabric and construction and the green one seemed to have the best construction so I went with that one and am definitely gonna get a few more now that I know my baby likes it. Hope this helps ## Features - TRANSITIONAL SWADDLE SACK promotes BETTER SLEEP and SAFER SLEEP.
