Sinah Mamadi can easily tell apart the children who don’t eat regular, nutritious meals at home, from those who do. They’re the quiet ones, she says. “They can’t concentrate. Some of them, they just don’t talk much. They can’t even play with other children. You can see they are weak when they come to school.”Mamadi knows the tiny faces of hunger all too well. She runs a two-room crèche for 115 impoverished children in the bleak heart of Makause, an informal settlement in Primrose, Germiston.
