More families arrive in Dunkirk each day and they would rather sleep in woods than seek asylum in France

“They are kids, so they are always playing. Like children in the UK play mums and dads or doctors and nurses, our children will re-enact boat crossings, getting patted down by the police, going to food distributions, meeting smugglers. Because one of the way parents safeguard their children is to present attempted border crossings as an adventure.”

In a nature reserve near Dunkirk, Caia Fallowfield runs a play project for migrant children who live among the trees with no running water or toilets. These are the children who vanish overnight off the French coast and reappear on the front pages of British newspapers, being pulled out of dinghies in Dover, often cold, wet and frightened.
