Six months after a devastating earthquake struck Haiti, Raphael Rowe returns to uncover what has happened to the country's orphaned and abandoned children. There are more than 400,000 children now living in Haiti's orphanages. Many of those rescued from the rubble are still unidentified or have simply been abandoned by their parents. Panorama meets others still living on the streets and asks whether meeting the demand for them to be adopted in other countries is really the best answer.
