A teacher from Cambridge features in a powerful ITV documentary tonight about refugee orphans stranded across Europe.
Sadie Clasby, who's 26, has set up a school with her mum in a migrant camp in Bulgaria, close to the Turkish border.
She says many of the children are so traumatised they've forgotten how to play. Natalie Gray reports. The Forgotten Children is made by Wild Pictures and is on ITV at 9 tonight.
