Description

The HALO Sleep Sack Swaddle replaces loose blankets in the crib that can cover your baby's face and interfere with breathing. In addition to helping your baby sleep safer, it helps him sleep better, too. Its adjustable swaddle wrap immobilizes your baby's arms to prevent the "Moro" or startle reflex. And, it is the only 3-way adjustable swaddle that adjusts to your baby's sleep style. Swaddle arms in, hands-to-face, one or both arms out to ensure baby's best sleep and an easy and gentle transition to the Sleep Sack wearable blanket when it is time to stop swaddling. Used in hospitals nationwide, the Halo Sleep Sack Swaddle is the 1 choice of hospitals and is recognized as "Hip Healthy" by the International Hip Dysplasia Institute. Its strong adjustable fasteners ensure a perfect fit and resist breakouts for more secure swaddling. Plus, its innovative zipper, unzips from the bottom allowing your baby to stay swaddled for easy diaper changes. HALO also proudly supports non-profit organizations like First Candle/SIDS Alliance. Use over regular sleepwear to take the place of loose blankets. Discontinue swaddling when the baby shows signs of rolling over or breaking out of the swaddle wrap. 100% cotton interlock.

  • Soft, and Breathable
Color: Jungle Size: Small (Pack of 1)
This is a great swaddle. Easy to use and no complicated folds. 100% cotton so it is breathable and not too hot but keeps baby warm and secure feeling. I think every grandparent or parent who wants to be able swaddle quickly and securely should purchase one.

  • Great quality
Color: Serengeti Zebra Size: Newborn (Pack of 1)
Honestly love the versatile of the swaddle my baby loves it so much and he is two months old. I can either put his arms in or out, and it makes him feel like he has a blanket on them great product.

  • Love this
Color: Baby Blue Size: Newborn (Pack of 1)
These are amazing. Our baby busts easily out of a muslin blanket swaddle, but the velcro stays put! He can sometimes get his hands up but it still prevents the jerking awake which is the whole point. Strongly recommend. Also note that if you go to the halo website, they have charts of how to dress your baby underneath the sleepsack according to your house temperature, which I found hugely helpful. Be aware when washing these in a machine to attach the velcro and put it in a mesh bag, otherwise it can catch other clothes - the velcro is quite strong. ... show more

  • 4 stars for new parent sleep
Color: Clouds Size: Newborn (Pack of 1)
Pros: - Helped our newborn, and award winning escape artist, get to sleep at the start. - Easier to use than a muslin cloth - Multiple options with hands in or out - Worked better than the love to dream sleep sack for calming, in our case Cons: - Velcro will destroy any fabric it touches in the wash, including if it sticks to the halo outside of the portion it was designed to stick to. - Way too big for 50th percentile newborn, need to be careful with wrap placement so that it doesn't cover the face with movement. It's possible to work around this with careful Velcro placement. - Some babies figure out how to get arms out before month 3 no matter the tightness or wrapping technique ... show more

Color: Clouds Size: Small (Pack of 1)
Love this. Keeps babies swaddled tight for comfort while sleeping. Breathable material and double zipper perfect for diaper changes in the middle of the night. Easy to swaddle. I’ve tried so many brands and this by far takes the cake

  • Best swaddle ever!

10/10. By far one of my favorite swaddles! I have tried many and this is top tier

  • Great for Strong Babies
Color: Heather Gray Size: Small (Pack of 1)
Highly recommend this for Moms with strong/big babies! My 2mo. boy busted out of every swaddle we tried - either his arms would wriggle out of the bottom or he would bust through the velcro entirely - but these work perfect! Easy to swaddle baby, velcro is strong and the flaps are longer than most to prevent hands sneaking out of the bottom, and the bottom zipper for diaper changes is a plus! Fabric is a little thinner than other swaddles so I just put a slightly heavier outfit on underneath for nighttime sleep just in case. 10/10 recommend! ... show more
