Traditional infant sleep positioners—like baby nests, docks, pods, pillow loungers, and crib wedges—are unsafe! These products feature dangerous bolsters, wedges, or pillows that babies can roll onto—or turn into—and suffocate. (Babies are often not strong enough to get themselves back to a safe position once rolling into a dangerous spot.) Unlike risky infant sleep positioners, SNOO does not have the pillows, cushions, or bolsters that are associated with suffocation deaths. Instead, SNOO features a universally recommended flat, firm sleep surface—and it's the first—and only—FDA cleared infant sleep positioner that keeps sleeping babies on their backs for all naps and night sleeps.
