I'd look anywhere your dd can get into/open, etc. Toy box, freezer, in people's shoes, in the cabinets, closets, etc. I lost my wedding rings last year, and found them on the floor of the closet. Best as we can figure, the cats knocked them off the dresser and batted them in there.
And yes, I kept going back and looking on the dresser, like they might magically appear there. LOL Good luck!
