He's now at Kuwait's Ibn Sina hospital, which has a special clinic for treating burns.
Seven other Iraqi children are being treated there too.
More kids need urgent help
Ali was the only member of his family to survive when a bomb hit his home, but has very bad burns to his body.
He had to moved because the hospital he was staying at in Baghdad didn't have the best equipment.
Many hospitals can't cope with the number of war victims, and some don't even have clean water.
Help from Kuwait came after Ali's nurse wrote to Tony Blair and George Bush asking for urgent help.
