Conflicts in countries in the Middle East have forced millions of people to leave their homes, and come to Europe.
Many come to escape the fighting in their own countries and get a better life.
Thousands of children have ended up in Greece, where they're waiting to move on and find a new home.
Ayshah went to Greece, to meet some of the children still waiting there, and talk to a lady who is part of a team trying to help children on their own.
