Uba, 23, left her abusive husband last year while she was pregnant and has lived in Aweil East, northern South Sudan, ever since. Currently, Uba earns the equivalent of £1.80 a day working on people’s farms, but says they can go three weeks without being able to buy food, during which her neighbours give her any they have spare. Today, all Uba has had to eat is sorghum – and she is breastfeeding her youngest child, Bilan. ‘If I cannot breastfeed, my baby cries,’ she says. ‘Sometimes I can get a lot of dizziness. There is not enough milk if I have not had enough to eat’
