Wish I knew the answer to this one! My DD eats everything - sticks, leaves, grass, dirt, sand, paper, bits of stuff on the floor, her clothes, playdoh, crayons, soap etc. She's not quite as bad as she used to be (growing out of it hopefully) but I still have to watch her closely in the bath (soap) and at the beach and park (sand and bark)
ETA to add - not quite everything, she doesn't eat her dinner most nights!
