This time last year, my DS had icky chewed shirts more days than not, and my DD, going into K, was picking up the habit from him. I got each of them a chewy pendant and insisted they wear it to school; after a while the habit seemed to die down (I don't really credit the chew toy, but a better school year and some maturation). Now, I dig the necklaces out once in a while if we're watching a suspenseful movie (this seems to be about the only time now that they revert to chewing). Googling the keywords chewy mom bling should get you to the thing, if you're interested. They're not ugly smile

We can't do gum (orthodontics).
