_A Walk in the Forest_ introduced the enormously talented Maria Dek, and _When I Am Big_ is a beguiling follow up to her first success. Charming illustrations and text encourage young children to explore what they can do as they grow up. The adventurous child imagines "I will tie my shoes all by myself, make 3 knots with big bows"; to eat twenty pizzas in one sitting, or walk animals, eight at a time, while teaching them tricks. _When I Am Big_ is also an unconventional counting book, as it goes all the way to twenty-five. The result is a book that nourishes a child's curiosity, confidence, and delight in the world's wonders.
