  • Great product
Color: Gingham Blue Size: Small (Pack of 1)
Love the versatility of this sleepsack! It’s warm, comfortable and easy to use. This is also a great way to help baby transition from swaddling to not swaddling.

  • Worth the price
Color: Block Flower Size: Newborn (Pack of 1)
Used one in the hospital. Immediately bought one when we came home. So much easier than swaddling and so warm for baby. Super cute pattern too. Washes well. Great quality for a winter swaddle.

  • Great For Baby
Color: Cozy Pandas Size: Small (Pack of 1)
This sleepsack is very well made with adorable patterns and incredibly soft fabric. It keeps our baby warm and cozy, and the material is sturdy enough to gently hold his arms in place without waking him. Since we started using these, he’s been sleeping so much better and rarely wiggles his arms free. Highly recommend for better sleep and peace of mind! ... show more

  • Cutest softest swaddle
Color: Sunshine Winnie Size: Newborn (Pack of 1)
We absolutely love this HALO swaddle in the adorable Winnie the Pooh print! 🐻🍯 The fleece is incredibly soft and cozy—perfect for keeping baby warm during cooler nights. I love that it’s versatile—you can use it with arms in for a snug swaddle or arms out as a great transition sleep sack. It’s well-made, easy to zip, and washes beautifully. Our little one sleeps so soundly in it! ... show more

  • Perfect for older infants!
Color: Baby Blue Size: Small (Pack of 1)
I bought this as a replacement for a smaller size I had from a second-hand store. This wrap is awesome! My son just turned 3 mos, weighs about 15 lbs, and is about 23 inches. He is in size 3-6 mos clothes, and still sleeps so much better when swaddled. The sizing is perfect for an older infant, not too tight, and has room to stretch and kick his legs inside the sack with 2-3 inches to grow. I love that there are multiple ways to wear this with his arms pinned to his sides, or with hands up near his face since he has started to self-soothe by sucking on his hands, or with arms out with the wrap around his middle for those chilly mornings. The upside-down zipper makes for easy nighttime diaper changes so I don't have to take him completely out of the wrap to have access. However, I always have trouble lining up the zipper correctly when initially placing him in the wrap, especially in a room lit only by night light and he is squirming, kicking, and fussing. There has also been a few incidents where the zipper became partially separated while he was wearing it overnight, and I had a bit of trouble getting it to unzip to take him out of the wrap in the morning. He usually just wears a cotton snap-up sleeper underneath and it keeps him the perfect temperature, since I turn down the heat to 67 degrees at night and always worry about keeping him warm enough, but I don't worry with this! He does get a little too warm before bed sometimes if he's fussy, as crying makes him sweaty anyway, but that tends to happen regardless so I usually just turn the ceiling fan on until he cools down a bit. And since I don't have to add a blanket on top at night to keep him warm, I don't worry so much about suffocation from accidentally getting a blanket over his face. The arm wrap secures with two long strips of strong Velcro that, even with his growing strength, he still hasn't managed to break out of. I plan to use this wrap over the winter instead of blankets at night, and like that it can transition with him when he no longer needs swaddled. A word of advice: When washing these, I place it inside a garment bag first (unless you intend to wash it separately) because that super-strong Velcro sticks to other clothing items and can snag or damage them in the wash. A garment bag will protect those cute little baby clothes! ... show more

  • Warm, good quality
Color: Heartline Size: Small (Pack of 1)
The fleece halow sack is great for colder temps. Soft, good quality. Giving 4 star because I feel the fit between the armpit to the swaddle wrap is a bit too tight & not a fan of the zipper needing to be connected (like a zipper jacket) at the top for each use.

  • Infant sleep sack
Color: Daisy Size: Small (Pack of 1)
This sleep sack was the only way I could get my baby to sleep for the first 6 months of her little life! The fabric kept her nice and warm in the northern utah winters and she slept so well! She would only wake once a night to eat and change her diaper. The zipper made it super simple to disturb her minimally to change. The fit was great and allowed us to use this longer term vs just a few weeks. ... show more
