The Transitional Swaddle Sack is the easiest & safest way to transition 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; and, if baby rolls over during sleep, the sleeves allow baby to use arms to lift torso and head to access air to promote safer 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. 100% Cotton. Soft, stretchy cotton knit. 0.7 TOG. Machine wash warm and tumble dry low. US patents 11,812,795 & D833,613 with patents in EU, UK, CA, CN, JP and other countries.

Our baby girl hated sleeping with blankets and they would fall off in the middle of the night. We started using these when she was 2 months old and honestly it helped put me at ease that her arms wouldn't be cold as she was popping them out no matter how tight we wrapped her in blankets. The sizing is accurate for our baby, so I followed that and would buy 1 or 2 at a time for her sizing to alternate them each night. The zipper was super easy and nice to use for late night diaper changes. She has been sleeping through the night since we used these so I cannot recommend them enough! It is worth a try if you have issues with blankets or sleep. The arms also give your baby freedom to move if they turn at night.

I liked this swaddle/sleepscak, especially for the price. It was a great transition from traditional swaddling to hands and arms being able to be free. It was easy to do diaper changes with the double zipper. Material felt high quality and comfortable to the touch. Highly recommend.

Super cute and works well for my baby at 5 months. He needed something to just keep his arms still and not startle himself

This sleep sack shrinks in the dryer. It works well but would be better if it was weighted. I like this one because there isn’t Velcro like other sleep sacks.

This is a great transition swaddle. My baby started rolling at 3 months and she felt so secure with this swaddle we did not have any issues and she was able to fall asleep without any problems. Highly recommended if your baby was used to the newborn swaddle with their arms down.

I was looking for a long sleeve that I can put his arms in for the cold. As you can see in the photo does not cover but to the elbowMy baby is 3.5 months for referenceIt was also hard to put on I think arms I felt like it was not wide enough abs I had to force babies seem inMaterial and design are good and I love a zipperI would returned if I did not already washed it.

This sleep sack is fantastic! It’s cute and my baby boy loves it! Sleeves are long enough that he can still touch his face, but not enough to startle. Zipper quality is really good! It is super easy to use, it’s long enough that getting a wiggly baby in isn’t a struggle!

As a newborn it fit well but At 3 months this sleepsack’s arms are way too short. They go to his elbow.
