It used to be you could find a box of photos or keepsakes that you inherited to look back on how things were or when you were a kid. Now, most of that is stored on phones, and most parents probably don’t think to share or save them in a way to be passed down in the future.
This here. Another thing to do is if you are taking video of family moments, narrate in the background what’s been going on for the past few days or a week. It adds additional context that is invaluable and would most likely be lost to even the person filming.
