Once a year I go through my photos and select my favourites and have them printed to paper. Using Google's print service (as an example) you can spend about $80 to have 150 photos printed into a book. If you do this once a year you will soon have a lovely shelf of paper photos you can easily store, easily look at and show to other people and hand down to your kids and their kids, etc. Long term I suspect my collection of books is far more likely to survive than my google account.

We got rid of my mom’s family photo books. Nobody has space / desire for 50 pounds of photos unfortunately. We use a rotating electronic frame now to cycle photos.

Long term your kids will probably wish they were digitized as well
