Jordanian officials have said that two-thirds of the Syrian refugees fleeing into Jordan across the border are women and children.
For some Syrians, it has become too dangerous to stay, but just as dangerous to leave.
Families who have been separated were picked up by Syrian opposition fighters when they could no longer walk, and brought to the border.
Yet, as the Syrian government sends more troops to the border, it is getting harder to get out.
