Two days ago we shared Frans Hofmeester’s wonderful time-lapse video of his daughter aging from birth to 12 in three minutes. That video has gone viral on the Internet, receiving a whopping four million views in less than a week. Hofmeester is actually doing the same project for his son Vince: the video above shows the boy aging from birth to age 9 in two minutes.

After his daughter Lotte was born, Dutch photographer Frans Hofmeester began creating weekly videos of her to document her growth. Lotte recently turned 12, and Hofmeester decided to edit all the footage so far into this amazing time-lapse video showing twelve years of growing up in just under three minutes.
