Depending how early they are born, premature babies can have the fight of their lives the very second they arrive in the world.
If a baby's organs haven't properly formed they may spend weeks or months in an intensive care unit.
A Quebec based photographer, Red Methot, has created a powerful series of images of people of all ages holding photographs of themselves as premature babies.
