You didn't say she wasn't using the box. Only that she is eating it. I agree that changing to a different litter could solve that. But is she using it otherwise?

Congratulations on your new kitten! I would first change you brand of litter. Then you will probably need to limit the space your kitten has to run from the litter box. Cats are naturally clean animals and she will seek out the area to eliminate. As a last option, you could try bringing a "dirty" bit of litter from another cat's box to give the kitten the idea that this IS the appropriate place. :)
