> Because it was significant, you keep recalling it regularly, maybe every week or so.
That's not how two year olds work. Even something as significant as losing a (or both) parents is still not significant enough to be recalled periodically, and we have many cases of that to support the hypothesis that "that's not how two year old brains work".
> I have a couple of such early memories which I believe survived through this recall mechanism.
I'm still skeptical. The first reason is that two year olds don't understand the concept of age in years (or age at all, TBH - they recognoise larger people and smaller poeple, but hafve no conept of age). The second reason is that the odds are very much against your hypothesis.
I have maybe ... two memories which I think were from age 2, but before age 3.
But I cannot determine if I was three or four at the time, instead of two. I cannot determine if they were real or a dream (because they are memories of an event of such non-significance[1] that no one else remembered).
I also cannot determine if they were not real and not a dream! I cannot tell if I "remember" them purely because when I was older my mum used to talk about the place they lived in when I was born, and with all the details, 6yo me simply interleaved actual facts with something my mind made up so that my made up memory is consistent with the facts I heard.
So, yeah, very skeptical when people tell me they can remember being two, because the odds are very much against it, and I say this as someone who has "memories" from 2yo, and I don't believe that those memories are, in fact, the memories of a 2yo me.
Not even a little bit.
[1] Memory #1: being taken to the bathroom one morning by an aunt who sometimes lived with us (and so babysat me quite often and would have done this quite often). I only have a memory of it happening once though, even though it must have happened at least a hundred times.
Memory #2: Looking at a patch of grass with a path that lead to the landlords house (also on same property, I was told when older).
With either of these, I can't be sure if I was 1, 2, 3 or 4 years old at the time. I also cannot tell if either was a dream, and if it was, was it a dream I had at 6yo, dreaming about being 2 yo or was it a dream I had when 2yo?
