"Guess How Much I Love You" follows the bedtime adventures of Little Nutbrown Hare and his father, Big Nutbrown Hare. As Little Nutbrown Hare gets ready to go to sleep, he asks his father just how much he loves him. Big Nutbrown Hare tenderly stretches out his arms as wide as he can and answers, “I love you as high as I can reach.” But Little Nutbrown Hare thinks he can love even more than that, so he stretches his smaller arms up as high as they can go. And so begins a loving competition between father and son as they continue trying to outdo each other in expressing the depth of their love.
They jump and reach, stretch their arms and legs, all in an effort to demonstrate the vastness of their affection for one another. Finally, Little Nutbrown Hare yawns an enormous yawn that makes Big Nutbrown Hare chuckle and scoop him up. He gives his little one a kiss and squeezes him tight as he reiterates that he loves him right up to the moon, closing their competition in a tender moment full of warmth. As Little Nutbrown Hare finally falls asleep nestled in his father’s arms knowing how he is so completely cherished, this classic bedtime story comes to an end.
