My sister was needing a device to help her baby sleep at night. I didn't know what she was talking about till I stumbled across this 36 SOUND PORTABLE WHITE NOISE MACHINE SERENE ESCAPE.  She freaked out.  She couldn't believe that I found the one device that had the most sounds that made her little one fall asleep by. 
She loved how it came with a USB charger cord and played for hours. Now my sister can adjust the volume and get plenty of rest because of the 36 SOUND PORTABLE WHITE NOISE MACHINE SERENE ESCAPE.
This is one Device that I am telling all my family and friends about for their babies.
