    • Love This Swaddle—Instant Sleep & Adorable Design!
Color: Ivory Strawberries Size: Medium
Review Image by A7T3C A7T3C
I am so happy with the Baby SNOO Sleep Sack! From the very first use, it made a huge difference in how quickly our baby falls asleep—almost instantly after being swaddled. I’ve used it ever since my daughter was brought home from the hospital. The quality is outstanding. The 100% organic cotton is soft, breathable, and feels so gentle against baby’s skin. I really appreciate how well it’s made—it gives me peace of mind knowing our little one is safe and comfortable through the night. Love the strawberry design it’s just the cutest thing ever! ... show more

    • Easy, Secure, Cute, and Baby Approved !
Review Image by Danielle Cloutier Danielle Cloutier
This swaddle is way better than the standard white one that came with our Snoo. The material feels softer and sturdier, and my baby clearly prefers it — he settles faster and sleeps more soundly in this one. The zipper is smooth, it’s easy to wash, and it holds up great. Definitely worth getting as a backup or upgrade to the original. Sizing runs true, so if your baby is on the longer side, you might want to move up to the next size sooner than expected. Overall, this swaddle is a total win in our house. It keeps our baby safe, soothed, and snuggled — and that means a lot more sleep for us too. ... show more

    • Even better than the old model!
Color: Ivory Planets Black Wings Size: Medium
At first I disliked these and favored the older ones that didn’t have the in between the leg Velcro but I’ve come around on them! I like that they encourage the legs to frog out for proper hip development - it also seems to help tall babies stay in the snoo longer. Two small cons: I like to put a heating pad in the snoo to preheat it before bedtime. The Velcro on the tail piece is sticking up so it always attaches to the heating pad. Not a huge deal but hard to detach one handed when i’m juggling a sleeping baby. The second con is I have found that these take a while to dry in the dryer. I usually have to put them in for 30-45 mins extra. The back band that secures the sack to the snoo is the culprit here. Pros definitely outweigh the cons tho! Great product. ... show more

    • Great product, bad smell
Color: White Size: X-Large
Works fine. Fits the snoo, but had a bad “packaging” smell when it arrived. Had to wash it twice.

    • Nice fabric and Velcro hold
Color: Midnight Planets Size: Medium
Strong Velcro to hold baby’s arms in place. Product recommends air drying which takes a long time due to thicker fabric. Recommend having two so one can be washing/drying while using spare.
