OK, I must admit, Jimmy likes food. He's gobbeled down everything that we've ever given to him. We finally found something that he doesn't like. It's a Stage 3 food, so that may have had something to do with it, but he gagged, and spit, and whinned, and made funny faces. So we relented, and dumped it. He seemed much happier with his rice cereal and juice. Silly boy.
