BTW, while we're on about 0-day photographs of babies, here is something very cool that some friends of my aunt's did: go and buy 21 identical A4-size picture frames. Put (your best effort at) a 0-day baby photo in one of them. On her first birthday, take a photo of her holding that photo; put that in the second frame. On her second birthday, take a photo of her holding the first-birthday photo, and so on. My aunt's friends had complete 21-photo sets hanging on their walls for both of their grown-up children...
