A team of travelling doctors is transforming the lives of thousands of Thailand's poorest children.
The youngsters all suffer from cleft palates, or harelips, and their parents can't afford the cost of corrective treatment.
But under the "Smile for Fathers" program, the children are getting free medical care to help them look and feel more like other children their age.
Cleft Palates and harelips. It's a condition that's both distressing and disabling.
It can make eating difficult, cause deafness and can badly hinder the development of proper speech.
In Thailand's far-flung Sisaket province, many parents live on the poverty line, and because the condition is not life-threatening its something most poor children have to live with for the rest of their lives.
It's these families that the project is targetting.
Called "Smile for Fathers" it brings together military and civilian doctors, who are putting their own money into the project. A large charity is also donating money to the cause.
Treatment is not difficult, but can have tremendous impact on the lives of those who need it. And it's free.
