A zip-up sack that swaddles babies in their natural arms-up position — a lifesaver for infants who fight a traditional wrap.
Some babies simply hate having their arms pinned. The Swaddle Up lets them sleep hands-to-face in the natural 'W' position while still limiting the startle reflex, and it's a straight zip — no wrapping technique to fumble. The wings are removable so it doubles as a transition tool out of the swaddle. Pricier, and you must size up promptly, but for arms-up babies it's transformative.
