This smart crib gives parents more sleep by soothing their crying babies and keeping them safely on their back. The Snoo was created by pediatrician Dr. Harvey Karp. In the parenting world, he's renowned for his baby-whisperer superpowers. His book, The Happiest Baby on the Block, and the companion DVD gives parents the "Five S" approach to soothing a newborn: swaddle, side or stomach position, shush, swing and suck. His methods are based on the notion that the first three months of life are more like a fourth trimester of pregnancy, in which the baby still needs to feel like they are in the womb. Karp's approach was the basis for the bassinet. He worked with MIT Media Lab trained engineers and designer Yves Béharto turned his Five S method into a device that mimics the womb by using technology to swaddle, swing and shush babies back to sleep. It may look like a fancy bassinet, but the Snoo is full of tech, from top to bottom. It has three microphones, a speaker and two motors that create different rocking motions.To turn on the Snoo, you have to swaddle the baby in one of the Snoo's sleep sacks and clip the sack into the sides of the bassinet. This is to ensure that your baby won't roll over in the middle of the night. Once the baby is in place, you start the Snoo with a button on the base or with the Snoo iOS or Android app on your phone. This will initiate a gentle rocking motion and a soft white noise that sounds like rainfall.If it starts to fuss, the built-in microphones will pick up the baby's first cries and signal the motors to intensify the movement and the speaker to change the white noise to a higher frequency that's supposed to help calm the baby. It will continue to bump up to the next level until it reaches level 4. If the Snoo succeeds at comforting your baby, the bassinet will slowly decrease to the default base level. But if your baby continues to cry past level 4 (because they're hungry or need a fresh diaper), the Snoo will shut down and send you a notification alerting you that your baby needs attention. The Snoo companion app allows you to control the bassinet remotely even when you're not connected via the same Wi-Fi network, which is helpful once baby is sleeping in his or her own room. Thank you in advance for the gift of sleep :)
