Immacula Jeanty, 42, whisked up a meal within seconds of receiving our supplies, feeding her children a local dish known as la bouille made of flour, sugar and water.

Her son, three-year-old Peterson, was going for it, downing spoonful after spoonful, scraping drops off his trousers, not stopping once. And when he was done, he flopped back on to a cushion. That boy was hungry.

Immacula's been in this temporary shelter on the hillside in Mariani for the last two weeks with Peterson and her eight-year-old daughter Jessica.

Her husband went out on the day of the earthquake and she hasn't seen him since. She looked traumatised.

"When the earthquake happened, even if I could find food, it wouldn't go down," she said. "I just tried to eat, so as not to die.

"When my neighbhours cooked, they brought me a bowl of food because I didn't have anything."

"I used to have everything a woman needs. Now look at my living conditions."

She was one of 381 families receiving food that day.

People in this camp had organised themselves in advance, with coupons, ready to receive food.. People are watching eagerly as the food is distributed but they're orderly and calm.

The family next to Immacula are busy hammering together some wood they've just found. Others are washing. A child laughs.

The camp is cramped - everyone is cheek by jowl and the sound of generators, radios and children fills the air.

There are women sitting around in curlers, men shaving, others playing dominoes, signs of normality in stark contrast to their surroundings.

Discussions will have to start soon on how people can begin to get back on their feet again. The future is unimaginable - the sheer scale of help needed enormous; but today at least one little boy went to bed having had some food.
