The only thing better than naptime is naptime with a friend. Theo the puppy (part-Boxer, part-Shepherd, part-Labrador, part-Sharpei) was rescued by Beau, a twenty-three-month-old toddler, and his family from an animal shelter in Santa Cruz. The two of them instantly became best friends. At naptime, Theo waits for Beau to fall asleep, then curls up next to him - a beautiful image of friendship and trust.Theo and Beau are already a viral sensation thanks to the "unbearably adorable," "utterly charming" photos that author (Beau's mother) Jessica Shyba has been posting on her popular blog Momma's Gone City. And now, she's combed through her pictures to find the very sweetest and matched them to a charming bedtime story to make a picture book that is (as Alyssa Milano said of the blog) "so cute it hurts."
