Oops. DD begged to do the puzzles again and, when she got to the 9 piece jigsaw puzzle I said, "That one is too hard for you." No it's not, she said. "It's too hard: it's a jigsaw puzzle," I said. No, it's a *train* puzzle, she said. Anyway, she did it swiftly. I opened up the large-scale 25 piece dinosaur jigsaw puzzle again and she could do that, too, all by photo pattern recognition with the "map." I stand corrected (by my toddler).
