Halo Sleep Sacks Review – A wearable Baby Sleeping Bag (including size chart)

Halo sleep sacks are wearable baby sleeping bags worn to bed as a blanket. Worn like a sleeveless jacket, the halo baby sleep sack has a zipper down the front that closes the sleep sack and secures the blanket to the baby.

Though usually not on any new parents "must have" list of baby needs, after the difference it made getting my baby to sleep, it's on the "must give" gift list for any new parents I know.

A Halo sleep sack is worn by the baby, it prevents blankets being tossed off during the night and your baby awakening from being cold. And more sleep for babies, and by extension their parents is never a bad thing!

The extra sleep alone makes buying a halo Sleep Sack worthwhile!

Halo sleep sacks are ideal for your baby once they have passed the stage where their jerky arm movements wake them from sleep. If your baby still wakes themselves by flailing their arms the Halo Baby Swaddle Sack may be a better choice.

We credit the Halo Swaddle Sack with increasing our baby’s night time sleep hours between feeds from 3 hours to 6 hours. No matter how tight we swaddled our baby, in a traditional rectangular baby wrap, she managed to get her arms free and wake herself. A halo swaddle sleep sack changed this, and we all go a lot more sleep. By 10 weeks our baby was sleeping through the night in a Halo Sleep Swaddle sack.

Sleep sacks, or baby sleeping bags have become popular as they reduce two of the risks associated with SIDS (Sudden Infant Death Syndrome)

In keeping with the SIDS prevention advice to remove all blankets, soft toys, and bumpers from the crib for sleeping, The American Academy of Pediatricians recommends using a wearable blanket in preference to lose blankets in the crib to keep baby warm.

How do wearable blankets or sleep sacks reduce SIDS risk?

In keeping with the SIDS prevention advice to remove all blankets, soft toys, and bumpers from the crib for sleeping, The American Academy of Pediatricians recommends using a wearable blanket in preference to lose blankets in the crib to keep baby warm.

The concern with lose blankets is the ability for blankets to bunch near the baby’s face resulting in rebreathing of carbon dioxide which increases SIDS risk. The “back to sleep” SIDS campaign that encourages parents to put baby’s to sleep on their backs also reduced the ability of the baby to rebreathe carbon dioxide.

As a reminder to parents the Halo sleeping sack is embroidered with “Back is Best” on many of their sleep sacks

The Halo sleep sack is also sleeveless which prevents overheating, also considered to be another SIDS risk.

In an indirect method of SIDS risk reduction, Halo also donates a percentage of all sales of their sleep sacks to SIDS research and education.

The halo sleep sack comes in a range of colors, including prints, solids and a Disney branded range. Some of the options can be seen in the attached Amazon listings, but further options are available on Amazon.

Fabric choices vary from 100% organic cotton for warm weather to microfiber and fleece for winter.

Halo sleep sacks are available in a number of sizes, providing for almost all sizes of baby.
