Frankie the Fox like all Cloud B products, is a sleep aid - containing a sound box inside a snuggle stuffed toy. My baby would only go to sleep with some sort of white noise, and the only thing I had before Frankie the Fox was an app on my smartphone - and with baby now in another room, that was not ideal. Frankie the Fox has a good selection of sounds, two length choices, and he only takes AA batteries! My son loves Frankie, and I can tell when he has outgrown the need for the sound, he will still have use for this loveable little fox :)
