More than three million people have fled Ukraine in the past three weeks, according to the International Organisation for Migration.
Since the war began 73,000 children have become refugees on average each day - a figure which underlines the enormous hardship triggered by Vladimir Putin's decision to send his troops into Ukraine.
Over the course of the 20 day Russian invasion, that means 1,460,000 kids have had to flee the country.
Poland, which shares a long border to the west of Ukraine, has seen 1.7 million Ukrainians arrive since February 24.

Hungary (255,000), Slovakia (204,000) and Moldova (106,000) have taken the next highest number of people.z
The UK government has come under intense criticism over the past fortnight due to the perceived slowness when it came to paving a way into the country for Ukrainian refugees.

As of this morning some 10,000 Brits an hour are volunteering to take in a refugee from Ukraine, a Foreign Office minister declared today.

James Cleverly hailed generous Brits as the number signing up to express their interest in a new scheme hit 88,712 this morning.
He said he was "actually quite proud" the website crashed yesterday.
Brit sponsors will be paid £350 a month and have to offer their spare room for at least six months.
But critics have branded it a "DIY asylum" scheme as, when full visa applications open this Friday, applicants will need to know the name of the person or family they will take into their home from Ukraine.
Lisa Nandy, the shadow communities secretary, raised concerns over matching Ukrainian families to sponsors.
She claimed the government was suggesting people should advertise on Instagram.
“On his [Gove’s] tour of the TV studios, he suggested several times that people who are willing to sponsor a Ukrainian family need to come to the government with the name of that family who will then rubber stamp it,” she said.
“He can’t seriously be asking Ukrainian families who are fleeing Vladimir Putin, who have left their homes with nothing, to get on to Instagram and advertise themselves in the hope a British family might notice them. Is this genuinely the extent of this scheme?”
