Stacking

N loves his stacking cups. For a long time, he would get us to stack them so he could knock them down. Then he started putting the little ones into the bigger ones. Now, he's finally got the stacking part down. Well, kind of. He stacks the cups nicely, but instead of the largest on the bottom, with the open end pointing down, he starts with the smallest and stacks them with the opening pointing up! Basically flipping the whole thing upside down.
