A four-year-old boy who had his leg amputated was among children wounded after Typhoon Haiyan.
The charity Save the Children has been working in the Philippines to help sick and wounded children.
Workers have been at the field hospital in Tacloban, capital of the Philippine province Leyte, and it was there they met William who had suffered terrible injuries.
The youngster, who has had his name changed to protect his identity, underwent surgery.
A spokesman for the charity said: 'We are seeing some heartbreaking cases of children who are in need of serious medical help. There are many cases, including amputations and serious infections from open wounds.
'One of the children they operated on was a four year old boy called William who sustained terrible injuries to his leg during the typhoon.
Six British doctors, supported by Save the Children and UKAID landed in Tacloban on November 18 to work in a field hospital run by the Australian government.
Save the Children has launched a $30million appeal to help 500,000 people in the Phillippines.
The charity believes 4.3million people have been affected by Typhoon Haiyan which hit the island on November 8 killing more than 4,000 people.
£50million has now been raised for the Disasters Emergency Committee appeal.
The UK government donated £5million to the total and the Scottish government also gave £600,000.
The DEC has now helped 500,000 people by making sure they have clean water, sanitation, medical care and temporary shelter.
DEC Chief Executive Saleeh Saeed said: 'We continue to be humbled by the remarkable support the public have provided for this appeal. The country has given so generously.
