Yeah I have similar memories. By now they are memories of recalled memories, degraded like an old VHS tape. But I am certain they are real because they meant a lot to me when I was very young (but older than a toddler). I.e. I have toddler memories I often returned to as a young kid.

Maybe there is something to this kind of moment as being particularly memorable, because one of the distinct moments I can recall that I know had to have been before 12 months was playing on the floor with my grandfather. He had a stroke not long after, which is how I know this had to have been the timeline. I can see the 1970s carpet, I know he was there bouncing me around as you do with a baby, and then mom came around the corner. That stuff can't just be an implanted suggestion from a picture - it almost makes me wonder is there a kind of micro trauma of being separated from the adult and then seeing them again that provokes a memory to be generated? Is there something novel about this kind of moment that causes memory to kick in and capture the moment, even though I can't remember what I ate for lunch yesterday?

"The more I recall this memory, the more I can tell, I am recalling a copy of the memory rather than directly experiencing that memory. "

I feel that is very true. I have some memories from when I was young that aren't really clear to me. It's more of a feeling thing rather than something specific.

And every time I think on that I wonder how much my mind fills in that I didn't remember.

I also have one from when I was a baby.

A woman who wasn't my mother carried me out from a house porch into the sunlight with my head on her left hand (heart) side.

There isn't much more to it and I try to not recall it too hard and/or often because it's far too easy to add false detailing to it.
