Eek I must be pretty anal then!! At home Zander can have it back if it's inside, as long as it was dropped by accident, if it's thrown down, gone! If it's outside or we are away from home (and friends/family homes) he cannot have it back at all.

Having said that he has eaten dirt, sand, leaves and all of that other fun stuff but I just prefer that he learns that he doesn't eat things off the ground.
