Is there like a switch or something? Kids pass the two year mark and suddenly - snap - there are the tantrums, the throwing on the floor, the indecision game playing, the pinching, the finicky eating... It's amazing! Another switch that has been flipped is the "potty peeing" switch, brought on by the interest in wearing a "tecka" (cueca - underwear). No interest in doing the same for coco though. oh well.
