A Caldecott book, this is one of the absolute sweetest children's books in existence. The Daddy rabbit (ahem, "Nutbrown Hare") and his little boy rabbit are going about their little rabbit day talking about how much they love one another. Such a precious story, and perfect for settling a little one into bed. The "I love you to the moon...and back!" line is enough to reassure any child of their parent's love.
