Cox's Bazar is a fishing town in Bangladesh where minority Rohingya from Myanmar have sought refuge after being forced to flee their homes, reports SBS.
Aid agencies estimate 60 per cent of the residents there are children, including many who have lost their parents.
Anwar Hossain is a Rohingya refugee who escaped conflict in Myanmar and is now living in a refugee camp in Bangladesh.
Along with his wife and children, a lost child no older than three is also staying with them.
"When we were crossing the border I found this child stranded in a field. So I brought him back with me," he said.
"Since we could not find his parents he is staying with us as our family member.Though my wife is there for him he still cries for his own mother."
A new report titled Childhood Interrupted, launched by Save the Children, Plan International and World Vision, looks at the situation facing Rohingya children in the camps.
The report estimates that 688,000 refugees have fled from Myanmar's Rakhine State since August last year, following an increase in violence in the region.
Most have ended up living in tents in Cox's Bazar in Bangladesh.
