Singing is more than just belting out some lyrics for 4-year-old Parker, who has a sensory processing disorder. Normally, Parker keeps to himself and is shy to those he's unfamiliar with. His Aunt Allie is visiting his family in Columbus, Ohio where she taught Parker a fun rendition of "3 Little Muffins." This song is a source of hope for Parker and his family. Don't stop singing Parker, you are doing so well!
