After two days in a small Somali hospital, Abdiwali Abdi seemed to be groping his way towards some sort of recovery.

The two-year-old still weighed just 4.6kg (10lb 2oz) - not much more than a healthy newborn. But he had the energy to moan now, and his mother, Hawa, sat beside him on the bed, in the border town of Dollow, breastfeeding her two-month-old daughter and making hopeful plans to return to their makeshift camp on the dusty outskirts.
