"We made the switch and it’s drastically changed our mornings!" @brittanygarzillostephens 💓 Our AirSwirl Waterless Bottle Warmer gently rocks the bottle during warming to ensure no hot spots or air bubbles. 💓 Warms with only hot air—not water—so there’s no bacteria or scale build-up inside and bottles stay dry. Same technology used in hospitals! 💓 Works with virtually all bottles. Includes two rings that hold narrow neck and wide neck bottles.
