Overview

Description

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

It also has versatility to match your baby’s sleep style and stage of development. It has a bag-style zippered sleep sack with an attached, adjustable upper body swaddle that wraps around your baby’s arms and torso. You can wrap your baby with arms snugly at their sides, hands-to-face or with one or both arms free. Some babies sleep better in the more cocooned wrap, and others need access to their hands for self-soothing. Large, adjustable fasteners on the top part of the swaddle help you get just the right fit.

The soft, polyester micro-fleece of this version of HALO’s swaddle sack is super warm (rated 3.0 TOG). It works well in cold environments, but you will want to select a lighter weight swaddle for more temperate climates or if you keep your home heated at night to prevent overheating.

The HALO swaddle is embroidered with “back is best” on the front, reminding caregivers to always place your baby to sleep on her back. It’s meant to be used over PJs in the place of a loose blanket.

The roomy sack at the bottom allows your baby to move her legs 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 do remember to attach the fasteners 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 child into the main pouch. Then wrap the Velcro wings around each other, keeping your child’s arms under each wing as you go. See HALO’s video below for more details.

Amazing swaddle but not for tall babies
We love this swaddle we had the newborn and the small, only problem is our son is not even 3 months and he doesn’t fit in it anymore, he outgrew the newborn by the first month and the small at less than 3, his feet kick the bottom of the swaddle making him uncomfortable

Great for colder nights. This
Great for colder nights. This actually worked better for us while it was still summer, as we kept it cooler inside. Now that’s cooling off, we actually keep our house warmer inside, so prefer the cotton one.

Our newborn loves sleeping in
Our newborn loves sleeping in this swaddle. It is a warm fleece material but not too thick to cause overheating. We use it at night to differentiate between daytime and nighttime sleep and it has been very effective. The preemie size is significantly shorter than the newborn size. Our baby was 19 inches at birth and we transitioned to newborn size at 3 weeks. Baby has plenty of room to grow and I anticipate we will be able to use the newborn size for at least 6 - 8 weeks. Highly recommend this product.

This is the best one
This is the best one for the coldest room in the house. We use this when he sleeps in our room since we have the air conditioner at 68 degrees. He slept so well with this fleece and I definitely recommend this !!!!
