My toddler son and I worked diligently to put together our first book, My First Train Book and published it to the Kindle Store and the iBookstore. A short time later, my wife translated the book into Spanish and we published Mi Primer Libro de Trenes to the Kindle Store as well.
Almost as soon as the book was finished my son started talking about writing another book about fire trucks. He started naming off truck after truck. Who am I to discourage a child from reading and writing. So, we set off researching fire trucks and other types of firefighting vehicles.
