It comes as ministers from around the world are meeting for the first-ever Global Refugee Forum in Geneva.
On the Greek Island of Lesbos, almost 18,000 people are crammed into a camp that was originally built for around 2000 people.
Pregnant women, new mothers and their babies are some of the most vulnerable people in the camp.
One woman Zainab, who’s 8 months pregnant, spoke to our Global Health Correspondent, Tulip Mazumdar.
