Overview

Description

The HALO SleepSack Swaddle has the benefits of a traditional swaddle, but in a simpler design.

The Velcro wings make it easy to wrap the swaddle around your baby and keep their arms safely immobilized, preventing the startle reflex that can disturb rest.

As a bonus, the 2-in-1 adjustable design of the SleepSack Swaddle lets you keep baby’s arms inside or outside of the swaddle. This maximizes your baby’s comfort and eventually helps them transition smoothly out of full swaddling.

The HALO swaddle is meant to be used over PJs in the place of a loose blanket.

Design details include a zipper that opens from the bottom for easy diaper changes. The roomy sack at the bottom allows your baby’s legs to move freely, promoting long-term hip health (though some babies sleep better when both legs and arms are wrapped snugly).

Parents report that the HALO SleepSack Swaddle holds up well to washing, but remember to attach the Velcro to itself so it doesn’t stick to itself or other items in the wash. Stop swaddling when your baby shows signs of rolling over or breaking out of the wrap.

To use the HALO SleepSack Swaddle, first zip your baby into the main pouch. Then wrap the Velcro wings around each other, keeping your baby’s arms under each wing as you go. See HALO’s video below for more details.

This swaddle works great for
This swaddle works great for our son at 3 months. They’re soft, the Velcro is strong, and they hold up after repeated washing. He doesn’t love getting into it but sleeps snug and sound once he does!
