What the Product Does
Sleep Zipper Swaddle with Arms Up – Baby’s natural sleep position is with arms up, just like in the womb. However, traditional swaddle blanket swaddles babies with their arms restricted beside their body, causing them to wake, get frustrated, and try to get out of the blanket. baby sleep bag with sleeves allows your baby to sleep in her preferred position and reduces the risk of rolling over. This sleep sacks for babies 0-6 month will make your baby as snug as a bug.

It is easy to use and care for, soft and feels comfortable, and your little one will sleep well in it
We Care Infant Every Subtle Reflex – There’s a lot of research around the Moro reflex – it’s the startle reflex babies have where they open up their arms, outward almost like a bird, when they’re startled. And it will often wake babies up from sound sleep to cry itself hoarse.(We’ve all seen it, if you’re a parent). Having something to gently tug those arms up helps sooth a startled child. This swaddle sack does that, without restricting the arms of a child who hates to be swaddled.

|---|---|
| One-way zipper sleep sacks | Two-way zippers allow full access for diaper changes and arm positioning, but add complexity and cost to the zipper system |
| Non-knitted woven sleep sacks | Knitted fabric offers better stretch and comfort for movement, but may have lower durability under heavy use |
