Toe (Burma), July 14: Now, 12-year-old Twe Zin Win must try to play the role of mother. Every night, she lulls her little twin sisters to sleep with a soothing lullaby their mother once sang to them, before the storm swept away her parents forever. "Every night I dream about them coming back," says Twe Zin Win, huddled in a tiny thatch hut the orphans share with grandparents, who eke out a hand-to-mouth existence while she cares for her siblings rather than going to school. The three children are among a still unknown number of orphans coping with hardships, physical and mental, more than two months after cyclone Nargis raged through Burma's Irrawaddy Delta, leaving a trail of flattened villages and broken lives. In an impoverished, military-ruled country with a threadbare social safety net, aid workers are also warning that these orphans of the storm are targets of exploitation, including recruitment into Burma's Army which has been accused by the UN, the US and human rights groups of inducting thousands of child soldiers. "As I have seen from many other countries, including those in Asia and Africa, being orphans simply increases their vulnerability to becoming child soldiers, forced labourers, being trafficked or involved in sex work," says Ashley Clements, a spokesman for the US-based aid group World Vision. Because of such fears, agencies like World Vision working in the cyclone-devastated region are advocating placement of orphans with surviving relatives, like the grandparents in Twe Zin Win's case, rather than in orphanages.
