I was about 2 years old old when this happened. My family had just moved into a new house. I remember standing in the living room watching my dad direct the movers as to where to place the couches. Meanwhile, my mother was upstairs unpacking while my older sister was watching everything from the stairs.
I suppose this was easy to remember since this was a big event (moving).
I would say that my personality now is quite different than that of my childhood, so, in that sense, we're not really connected. From that aspect I would say that we were the same person starting from around middle school. However, I would say that I recognized myself when I was about 5 years old.
that's interesting because i didn't have any memories until i was much older (4 or 5 probably) and the one memory i can recall is one that never even happened. I guess there must be a certain amount of variance between when people have their first memory.
