I'd add, the "on this day" photo library feature is amazing as your kids get older and memories fade. Little video snippets (and live photos: priceless) from when your kids were 2, 5, 10 years younger. Searching for keywords from image/face recognition when you remember something and getting a real memory back.

Of course, there's a balance with living in the moment too, but as someone who forgets what happened yesterday, I try to document as much as I can.
