When I find a book I stick with it. I mean why bother trying something new if you already know what you like.
Thus, it is ironic that my favorite book that I demand Mommy read again and again and again is a life lesson book by Dr. Seuss that preaches trying new things.
There is a reason that "Green Eggs and Ham" is considered fiction. If you find something you like just repeat it. Be it a book you like having read to you or waffles and (Non green) pineapples for breakfast.
