I discovered this charming book while I was an undergraduate studying early childhood education and read it to preschoolers to get them to settle before nap-time. I can't recall the children's responses but I loved the story. And twenty-five years later, I still remember the message and some of the text:
Sometimes children will go on food jags. Wise and understanding parents allow children to learn for themselves that there really can be too much "bread and jam."
