I wish I knew more about this video – or could even remember where I first saw it. But in any case, you should watch it. It’s a time-lapse slideshow of a baby girl, soon joined by her baby sister, as they grow from infants, through the toddler stage, into children, and end up as young adults. It’s an amazing piece of work, and while I don’t have kids, I can imagine what a treasure this collection of photographs is for the girls’ family. If anyone knows who produced this, and who the girls are, I'd love to give them credit!
