Ryan Simpkins wrote Sitters Street when she was 9 years old. The idea started as she had sketched out some characters. When her friend Charlotte slept over one night the girls decided to turn Ryan's sketches into a story and Sitters Street bloomed.
Over the period of a year, Charlotte Barrielle and Ryan Simpkins wrote five "Sitters Street" scripts when they were only ten years old. The first "Sitters Street" was produced in 2009 when they were only eleven.
