Now that you know how you son reacts to criticism, why not just praise him but perhaps occassionaly mention one thing that could have made it a better story? Maybe this criticism will be taken on board for the next story he writes for you? What you definately don't want to do is to discourage him at this early stage, as to be honest, most of his work is disposable practice. Ask yourself whether you'd be critical of a painting he'd spent time making for you? Probably not. My own daughter is in a similar position. She absolutely loves the process of writing and producing a piece of work with illustrations for me to read, but like your son, when she'd finished, she's finished!
