I found these great little inventions, from Jellystone Designs these are bangles and necklaces that are 100% safe for bubs to chew on. They are non toxic, free from BPA, PVC, Cadmium and Lead. The Hip Infant are stocking them and they are all $15-$16. A great idea I think as I remember the kids always liked to drool all over my braclets and just about rip my necklace off to get them in their mouths.
There is also a new bead necklace coming soon.
