Is it the moon? Or Saturn? :)

We just finished learning about the planets and to my surprise Eliza really caught onto the idea of stars and planets.  In the past at night when we see the moon she has referred to it as, "Harolds moon". This is because she loves Harold's purple crayon, but now she affectionately insists that it is a planet.  The first time it was Venus, then mars and Saturn.  We are not allowed to call it the moon without little Eliza Jane insisting it is a planet.  A very ameture star gazers in the making!
