SwaddleDesigns Transitional Swaddle Sack, Arms Up Half-Length Sleeves & Mitten Cuffs, Swaddle for Newborn Transition to Baby Sleep Sack Wearable Blanket, Medium, 3-6 Month, 14-21 lb, Heathered Denim

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!

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

Nice material, really soft and breathable

Must have for a baby that loves sleeping with arms up. These were perfect for transitioning over to a sleep sack. Started with hands covered and then let her hands free at night. Once she was too big for a swaddle I moved her to a sleep sack seamlessly thanks to these. Great material, not too thick or thin. Has a slight stretch so cut can conform to baby and make them feel swaddled. Very easy to use because of the two way zippers as well.

I originally got the size small for my two month old, and I was gifted a couple of the exact same brand/style/size and they were bigger than the two I received. the different designs have different sizes it seems but these are otherwise great. They keep my baby warm at night and keep her from startling when I wake her up to feed her. It's very soft and a little stretchy (but compressing enough to have a bit of a swaddle effect which I love), and they're so cute. I just wish the sizing was more standard so I knew what size she'd fit best into.
