Yes! White noise machines are safe for kiddos of all ages! And white noise machines benefit babies, big kids, and parents by promoting sleep, which is always a win. It is just important to keep white noise at a safe level for your precious bub’s wee ears…and all of Happiest Baby’s white noise products—SNOO, SNOObear, and SNOObie—do just that. In fact, SNOObie was designed so that the volume automatically decreases when SNOObie is disconnected from the charging dock (please keep the device at least 15 centimetres from the ear).
