Listening and observing my daycare kids. Watching them play and asking them questions. One day, a child made a snake with playdoh and had a suitcase on his back. With that I made up a poem about a snake going on a trip across the other side of a field.
From my family mainly. Always Eat Your Flies came from the fact that when I married a few years ago, my husband was not a very good housekeeper. Cleveland, the Dirty Bird came from a family situation and seeing a group of geese flying over which had only one bird on one of the sides. Of course, he must be dirty and stinky for no one to be on his side.
