You know the moment. The baby finally drifts off, you lower them into the crib, and their eyes snap open like nothing happened. Back to rocking, swaying, and patting until your arms ache. That’s the problem Sleepy Baby was made for. Instead of only playing sound, this baby sound machine also gives a soft, automatic patting motion through a plush heart-shaped paddle, so you don’t have to keep going by hand. The speed is adjustable, which helps because no two babies like the same tempo. White noise is built in, so there’s one device doing two jobs instead of two cluttering the room. It comes with a belt to keep it in place and charges in around 1.5 hours. A small red blink tells you when it needs power, and a green light shows when it’s ready. Sleepy Baby is meant for newborns and up. It weighs only about 136 grams, so it’s easy to move around the house. If it doesn’t help, the 30-day money-back guarantee is there, which takes some of the risk out of trying it.
