Biscuit and the Lost Teddy Bear is a Level 0 ("My First Shared Reading") I Can Read! book that is, according to the back of the book, "ideal for sharing with emergent readers". It is intended for children who aren't yet able to read independently.
In a story aimed at the youngest of children, a puppy named Biscuit and his unnamed human friend stumble across a lost teddy bear. Over the next thirty or so pages, they seek out the child who lost the bear; the story is told through two or three short sentences per page, all of which feature very simple diction and grammar.
The book, and presumably the rest of the Biscuit series, is ideal for parents introducing their infants and toddlers to reading.
