I felt that many of the initial and easy words were missing in the book. And some unnecessary words (for the 1 year old) are added. Like how will a 1 year old boy differentiate between a helicopter and an Airplane. A car, tractor and truck? Why do we need a picture of Dog and Puppy, Cat and kitten. I think only one would have been enough. Instead of putting a carrot picture, carrot sticks which even I couldn't recognize. Pictures are too dark on a bright colored block. Disappointed.
