The number of people killed in Pakistan by the South Asia earthquake has now risen to 38,000, with 60,000 injured.
The number of people left homeless has also jumped, from 2.5m to 3.3m, according to the Pakistani government.
Really bad weather in the area has made it difficult to get aid to the places that need it most, with wind and rain keeping helicopters on the ground.
Now aid agencies are worried about the affect the weather will have on the homeless, especially the children.
Cold, a lack of food and disease are all big problems for children, according to charities Unicef and Save the Children.

Many of the worst affected parts of the region were really difficult to get to before the earthquake, so now things are even worse.
At least 1,400 people are also known to have died in Indian-administered Kashmir.
UN top relief co-ordinator Jan Egeland said billions of dollars would be needed for the aid effort.
Only $50m had so far been pledged from the UN target of $272m from the international community, he said.
