Great Day for UP

Part of Madelyn's bedtime routine is that we read her a story or two (depending on how long the books she chooses are).  Tonight she wanted to read "Great Day for Up" by Dr. Seuss.

On one of the pages it says "up you worms!"  and Madelyn asked Justin what a worm was.  He said "a small creature...they're wiggly...a worm is a multi-cellular organism..."  Evidently this is how we explain things to our 2 year old :)
