Paul Graham on Twitter: "Now that I'm the annoying parent always taking pictures rather than the child squirming at being photographed, I understand the source of the asymmetry. They have roughly the same parent their whole childhood, but at 4 we lose the 3 year old and have only pictures left."

  A wise friend with 4 kids told me - take more photos, you will never have enough. I'm terrible at taking photos. It's not even the 3 year old we lose, it's the 2.95 year old we lose and every stage between.

  Imo, age is experienced (or in your case, change is observed observed) at 1/age, so to a 3 year old moving to 4 it’s a 25% life move, while 50-51 is less than a tenth of that. YMMV.

  A friend writes the most remarkable things his son says or does, so he can remember them in the future.

  They’re also tied up in the urgency of NOW, while you realize the fleeting nature of now in the arc of life. Traditional Japanese culture has Sakura. We take photos.

  In a traditional extended family there were lots of closely related kids of all ages—many of whom resembled each other, so this was less of a problem.
