The Happiest Baby SNOO ($1,160) may be the world's most technologically advanced bassinet, incorporating Dr. Harvey Karp's famed five S's into product form. A beautiful sleeper on its own with a modern wood and mesh design, the bassinet features a mattress that produces white noise and "swings" up to one-half inch each direction to help lull babies to sleep. Hidden microphones detect a waking baby and signal the sleeper to respond with increasing sound and motion, basically providing the same response parents would when a newborn fusses in the middle of the night. Should a baby fuss for more than three minutes, the bassinet shuts off, signaling that the baby is distressed by something that needs parental involvement — a diaper change or a feeding.
But perhaps the most unique feature on the SNOO is the sleep sack Dr. Karp developed to ensure that newborns stay on their backs throughout the night. The SNOO Sack replaces the swaddle — which has a tendency to come undone, making new parents nervous about suffocation — with a tight sleep sack with "wings" that attach to the sides of the bassinet. Although the design is unusual, it's also practical, making it impossible for a baby to flip over onto his or her stomach overnight
