6/6. Soul Sisters. Three girls grapple with what it is to be female. Persis, nine, lives in a Welsh village. She is fed up being mistaken for a boy, but won't grow her hair or wear dresses. Seven-year-old India lives in south London. When everything gets too much, she escapes to an imaginary world. And Sheffield's Yasmine, eight, plays football and referees her parents' rows.
