    • Incredibly Functional Swaddle
Size: 6-12 pounds Color: Lavender
Absolutely love this product. Easy to use if you follow the technique they suggest. It keeps your baby’s arms away from their face and controls the startle reflex without squeezing them a ton which my kids haven’t liked. Bought this for my 3rd baby so I’ve really tried all the swaddles at this point and have really loved this. We used this right out of the hospital with an 8lb baby and since it is fall have had her in an onesie and booties underneath. Added bonus that the production process is zero waste and made in the USA. ... show more

    • Not for hot babies
Size: 6-12 pounds Color: Pink
My newborn absolutely hated this and I was so hoping she would like it. It looked like her shoulders were too tight around her body. She was 8 lbs so I was surprised. The material was not so breathable for a newborn as I thought it would be too. It’s very hard to put on as well. I wish I could return it because it’s pricey and we didn’t use it! ... show more

    • Good gift for expecting moms
Size: 6-12 pounds Color: Grey
Great invention. I got some as a gift for my sisters’ babies… easy to use and comfortable for your baby. Only reason it’s not 5 stars is my baby gets frustrated not being able to lift their hands more and has calmed sleeping other ways without the swaddlini anymore. Still a good product to ah e and share with others since moms ... show more

    • Don’t knock it
Size: 6-12 pounds Color: Lavender
Purchased this based on a recommendation from a friend. Initially, we found it difficult to wiggle on. We explored several other brands of swaddle but ended up returning to using the Swaddelini! Durable, stretchy, and soft on our sensitive skin baby. The small size is headed into its 4 month of use. Great value for the price. The baby has slept though the night using this, up to 9 hrs. Other bands only seem to get her about 4 hrs. ... show more

    • Soft and Cozy, But Too Big for Our Newborn
Size: 6-12 pounds Color: Lavender
We were really excited to try this swaddle, the material was soft, thick, and felt high quality. Unfortunately, it was much larger than expected for our newborn, so we had to return it. Hoping to try it again in the future when our baby grows into it!

    • Baby hated it
Size: 6-12 pounds Color: Lavender
Difficult to wrestle on my baby and she absolutely hated it. Also it would not be easy to change her in the middle of the night with it on.
