Here are some from an older book, FEED ME, I'M YOURS.

ROUND TEETHING BISCUITS

2 eggs
1 cup sugar
2 to 2 1/2 cups flour

Break eggs into a bowl and stir till creamy. Add sugar and continue to stir. Gradually add enough flour to make a stiff dough. Roll out between two sheets of lightly floured wax paper to about 3/4 inch thickness.
Cut in round shapes. Place on a lightly greased cookie sheet. Refrigerate overnight. Bake at 325 degrees until browned and hard. This will make about 12 durable and almost crumb free teething biscuits.

OATMEAL CRACKERS

3 cups oatmeal
1 cup wheat germ
2 cups flour
3 tablespoons sugar
1 teaspoon salt
3/4 cup oil
1 cup water

Combine ingredients and roll onto 2 cookies sheets. Cut into swaures and sprinkle with salt. Bake 30 minutes at 300 degrees or until crisp. Be sure to roll thin and bake well.
