Yes, the Cradlewise Smart Crib's movement is unique which allows you to safely swaddle your baby without the need for straps, fasteners, or positioners. Other smart cribs or swings move side-to-side which increases the risk of roll-over and requires the need for straps. The Cradlewise moves in a smooth up-and-down motion, much like when they are in the womb, keeping your baby safely on their back.
