The Happiest Baby Snoo is a crib that soothes a baby to sleep with a push of the button. The bassinet uses sensors and artificial intelligence to respond to a baby's cries. It rocks and plays white noise, adjusting the levels based on the volume of the crying. Parents can control it with an app that alerts them if their infant is inconsolable.

The crib also straps the baby in with a specially designed swaddle, lowering the risk of sudden infant death syndrome.

It's so effective at helping babies (and parents) get more sleep, that some companies even offer it as a benefit.

But for those that pay full price, it costs $1,295. The company is now renting it out for $4.90 a day, or close to $150 a month.

The crib is built for newborns and most outgrow it by the time they're about six months old. The Snoo is the brainchild of Dr. Harvey Karp, a pediatrician. His book "Happiest Baby on the Block" has been a bestseller since 2002.
