Contact your local library. Find out if Bread, Bread, Bread by Ann Morris is available. If it is not, get a list of books on nutrition for children from one to five years of age. You may want to put a copy of the book in your WIC lending library for clients to use. As you read the book to one and two year olds, they can participate by pointing to the pictures and the different things in them.
Older children can answer questions and talk about the book.
Show the children the cover of the book. Tell them the names of the author and the photographer. Let the children bring up topics and ask questions as you read. Pick one of these to do with the children in addition to reading the book. If you have refrigeration in the clinic, you could use mayonnaise on the bread.
