"Count Your Blessings (Instead of Sheep)" is a popular song written by Irving Berlin for the 1954 movie White Christmas. It is commonly performed as a Christmas song, although the lyrics make no reference to the holiday. The best-known recordings were made by Rosemary Clooney and Bing Crosby who both appeared in the film.
