In the more familiar territory of My Kitchen, the toneless Harlow Rockwell manner you will recognize from My Doctor, My Dentist, and My Nursery School is merely banal. At the infant stage--when pointing to the spoon, the bread, and the can of soup are all that can be expected of a child--this presentation is all that need be demanded of a book. A little later, when the child is up to such Sesame Street exercises as noting the drinking glass in the sink, the pots and pans in the cabinet, or the peanut butter on the bread, it will serve. But when it's time for reading all the coffee, dried beans, spaghetti, oil, and other labels (""So many things ale on the shelf?'), the blandness of the fare becomes the major consideration.
