Little Nutbrown Hare wants very much to impress Big Nutbrown Hare with the enormous scale of his devotion, but ends up being the one who's impressed. Subtitled "a pop-up edition," this sturdy square edition of Sam McBratney's ever-popular Guess How Much I Love You is probably better described as a "slide-along edition." Some pages do include pop-ups, but they aren't the best ones; instead, most involve pull-tabs which animate the two rabbits and their surroundings. One of the most appealing scenes simply shows Little Nutbrown Hare hopping up and down. In a purely technical sense this exercise in interactive cardboard technology is well behind some of the competition, but the tale has a timeless charm and the very simplicity of the movements makes it easy for small fingers to waggle the tabs and take control of the story.
