Clean floors... no longer

Ada has always been a good eater... she'll eat anything that you put in front of her with gusto and usually asks for more... in fact, we weaned her from a bottle without any fuss. But she had the flu last week and has been picky ever since... she throws most of her food on the floor and sorts her food into the piles of "will eat" and "won't eat". I don't mind a little pickiness... but what do you do about throwing food on the floor? She always manages to do it with the worst things right after I've mopped too. Jam, green beans, spaghetti, etc... I guess we'll keep working on this newest challenge.
