The Yogasleep Hushh Portable Sound Machine helps baby fall asleep – and stay asleep – anywhere. A white noise machine is a powerful tool in your infant sleep routine and helps baby fall asleep fast and minimizes sleep disruption from the outside world. It creates a constant, soothing sound that helps lull your baby to sleep by mimicking the sound of the womb. Once baby is asleep, white noise works throughout nighttime or nap time. The Hushh’s baby-friendly features like a soft LED nightlight, flexible clip, and child-safe locks have made it a parenting must-have and popular registry item. Now, with Hushh, we've made white noise even more convenient -- so you can take a familiar and comforting sleep sound with you wherever you go!
