We Know She's Done Eating When the Food Hits the Floor
One thing our daughter does that I'd love to get her to stop doing is throwing food on the floor. As long as she wants it, she'll eat, dropping only pieces that miss her mouth. As soon as she's done, she throws her plate, bowl, sippy cup, leftovers, etc., right off the edge of her high-chair tray. I hope this phase doesn't last too long.
