Found a new book for James' reading favourites:
Harold and the Purple Crayon. I loved this book too, when I was in grammar school, and made my own books about how I would use a magic crayon. I can't remember specifics, but mermaids, talking animals, and waterfalls made for exciting flights of fancy.
I can tell James was excited about this book because his reading grew almost as animated as it is for Where the Wild Things Are. I think James also enjoys being able to read a book out loud without too much difficulty. The strong visuals are appealing as well.
Meanwhile, we are down to the last 2 chapters in our Magic School Bus book!
