Two children with the same birthday may meet a story differently. One may enjoy listening to a longer read aloud; another may want to study the pictures, join in with repeated language or attempt parts independently. The gift buyer therefore needs more than an age number.
Begin with the intended reading situation. Who will usually hold the book? Will an adult read the complete text? Is the pleasure mostly in recognising the character, following the adventure together or revisiting familiar lines? Those questions produce a more honest recommendation than attaching every book to every age.
