NANYNOISE - White noise sleep machine 

Getting your baby to sleep shouldn't be a battle with every sound in the house. You need a way to help them settle down and stay asleep through the chaos.

NANYNOISE plays 10 scientifically-designed soothing sounds—white noise, rain, ocean waves, and more—to create a calm, consistent sleep environment that helps babies drift off and stay asleep.

Rechargeable, portable (perfect for travel), adjustable volume, and customizable timer (1-8 hours). Small enough to clip on the crib, powerful enough to actually work.
