Get the Best Fit for More Restful Sleep: To ensure a snug fit, we recommend sizing down in our transition swaddles if your little one is in between sizes. Sleeping Baby swaddles should have slight resistance when your baby lifts their arms Unique Starfish Design: The Zipadee-Zip transition swaddle features a distinctive starfish design that mimics the womb, ensuring your baby feels cozy and secure. Its ergonomic shape promotes better sleep by recreating the snug and comforting sensation of the womb, helping your baby feel more at ease Dual Zipper for Easy Diaper Changes: Featuring a convenient 2-way zipper which allows for quick and easy diaper changes, making nighttime routines smoother and less disruptive for both you and your baby Supports Proper Hip Development: The roomy design of our baby transition swaddle provides ample space for your baby's legs to move freely and naturally. By allowing unrestricted leg movement, this design supports the healthy growth of your baby's hips and ensures comfortable, safe sleep Encourages Longer Sleep: Suppressing the Moro startle reflex, our baby sleep suit helps transition your baby into arms-up sleeping, reducing interruptions and wake-ups for a longer, more restful sleep.
