Once upon a time the only keepsake from a nine-month pregnancy would be a slightly-blurry scan photograph, memories of morning sickness, cravings for bizarre food combos and... of course... a baby-turned-child-turned-adult.
But to hell with tradition. The digital-age - where the world tweets running commentaries of Downton Abbey and Instagrams pictures of their eggs Benedict - wants more.
Cue the time-lapse pregnancy craze, where expectant parents document their growing bump over a nine-month period - until out pops a littl'un.
Buenos Aires-based photographer Sophie Starzenski is the latest mummy to snap her tummy as part of a beautiful photo series '40 Weeks and a Mirror'.
The images, where she poses before her mirror with the camera hiding her face, combine the selfie and pregnancy progression portraits.
We love them. What do you think?
