A father-to-be created a touching pregnancy video documenting the size of his growing baby by comparing it to different foods.
Danny Bortfeld, an actor from Berlin, took a photo nearly every week of his fiancee Marlen Lalo’s pregnancy before they welcomed daughter Luna in April 2017.
The excited couple used seeds, fruits and vegetables to serve as visual comparisons for the size of their unborn child.
They then compiled the sweet snaps into a touching slideshow entitled ‘When love becomes life’, which went viral after it was shared on the official Netmums account last week.
