Just how clean is your kitchen floor. You sweep it daily (and sometimes more than once a day). You use the dust-grabber a few times a week. You mop at least once a week. It is clean. It has to be. But the true test comes in the form of ten-month-old legs crawling across it–exploring every nook and cranny. After passing over the kitchen floor, the knees on these legs are dusty. How can it be? So you find out your kitchen floor is not truly clean. But the best part is the one who examines it the most closely really doesn’t mind the dirt. She’ll just eat it to get it out of the way.
