I seriously remember breastfeeding. I remember sleeping in a crib beside my brother. I can close my eyes and tour every place I spent time as a child.

And like your sister, my brother remembers none of it. I’ll bring up something that meant a lot to me and he always replies the same, “I don’t remember that time.”

Like this one weekend. We rented Turner and Hooch, We’re Back: A Dinosaur Story, and Fern Gully. We intended to stay up and watch them so we pulled out the bed from the couch and instead talked until we fell asleep. We got up early and watched all three. My brother was nuts about the character Batty and wanted everything Robin Williams was in after that. He went around all day saying “are you sure? Are you positive? Only fools are positive.” I seen the cartoons only once and I still remember character names and plot lines.

I tear up thinking about that morning. Him, “I wish I could remember it.” And that’s his answer for all of it.

Now ask me what I did two days ago. My answer will be the same as his for what we were doing then. I legit can’t remember past yesterday.

Yeah writing down is a big help, I think it's too do with multiple things. You have to focus more on what you're actually writing. As well as you have chance for multiple memories, the thinking itself, think of writing it, actually writing it, the muscle memory of writing it, and then reading it again afterwards.
