I sure wish they'd had those chewy toys when I was a kid, but my mom would never have gotten me one! I used to chew on my shirts, necklace, hair, pencils, and the ever-present gum that I fell asleep with and ended up with in my hair so many times! Well, on the other hand, maybe my mom WOULD have gotten me one, after the umpteenth time of having to use ice or peanut butter to get gum out of my hair.... smile

I don't see anywhere near as much of it in my kids, though.
