Wow cyber, this sounds really good to me. Our SALT is desperately trying DS to be more expresive when it comes to books. He is now much better at sitting and listening to a story, and he will talk about things he can see on the page, but he still doesn't talk about the actual story.
I like the idea of a photo day - I could photograph each stage of the day and put it in a book for him and see if it gets him talking. This is such a new development that I have to take time to think it through. I have been trying all weekend to film a clip of him telling the story but needless to say without much success !
