I'm interested in getting a teething necklace (the kind for adults to wear, not the amber ones that babies wear). Have any of you tried these? Any recommendations? It looks like I have two options: a single rubbery pendant or GIANT rubber beads. I think more than one bead would be easier for my 5 month old charge to grasp and shove in her mouth. But I have an understated, simple style and am not sure I could pull off those big clunky ones. Plus, it seams like the beads in the back would pull out my hair. Anybody know of anything in between?
