Claire Lankford, 5, of Dickinson, Texas, is battling a rare form of cancer called Rhabdomyosarcoma.
There is no cure for the disease and her family is determined to cherish every moment they have.
Like many 5-year-olds, Claire is a big fan of princesses and fairy tales, so a family friend decided to give her the royal treatment in a big way.
Claire's "Princes Parade" was complete with a marching band, cheerleaders and a horse-drawn carriage ride down a street lined with hundreds of friends, neighbors and supporters.
Claire wore a princess gown provided by a local bridal store and even her parents got in on the royal fun - her mother dressed as Belle and her father as Prince Charming.
