How to use a 3-way swaddles?
Every baby has different sleep preferences. The adjustable HALO® SleepSack swaddle provides 3 easy ways to swaddle to ensure your baby’s best sleep and to help make the transition from swaddling easier.
What should my baby wear underneath?
It is essential to dress your baby appropriately underneath the sleepsack or swaddle, depending on the room temperature. Use lightweight, breathable clothing, such as a onesie or a light cotton sleeper, in warm weather. In colder temperatures, opt for a warmer sleeper or footed pajamas.
What is a startle reflex?
Swaddling creates a familiar and comforting environment for newborns, reminiscent of the cozy confines of the womb. The snugness of the swaddle provides a sense of security, helping babies feel calm and reassured. Also, newborns have a strong startle reflex that can wake them up abruptly during sleep. Swaddling can effectively limit the jerky movements caused by this reflex, promoting more peaceful sleep and longer rest periods.

"Nice material, but baby very easily gets out of the swaddle compared to the TOG 2. 0 that I purchased. Also the shoulder seams are very rigid, it’s hard to leave one arm out because it cuts into his armpit."
— Josselyn A. (2/5)
"Feels rough and flimsy, better off with cotton fabric"
— Ka V. (2/5)
"Don’t buy this unless you want to worry about your baby choking in the middle of the night. Constantly having to readjust it because they stir a little and the material rides up. Also just in daily use the fabric gets extremely frayed from using the Velcro and seams begin to tear. Not worth what they charge."
— Chloe (1/5)
"I ordered 2 precious swaddles that were great 2 way zippers. Then I got one in the mail with an inverted single zipper - completely in useable terrible design. You have to fasten it at the babies throat while wrestling arms…no thank you. Customer service said it was an old 2024 design and they’re just shipping all inventory and can’t guarantee the newer 2 way zipper design. TERRIBLE. Get rid of your old inventory and ship good products."
