I have a handful of early memories between like 4-7. But tbh, not 100% sure they are all memories vs. mental creations from hearing stories about me when I was young or seeing myself in pics along the stories. The human mind is an enigma.
This.
I also believe many of the "memories" I have of my very early childhood are from photo's I'd seen time and time again growing up, stories told of events, etc. Because when I try to think really hard, I cannot recall anything beyond those still shots in my head.
I am sure there is some of that, but I recall many different things from the time of 3 and under. I know that because of the events and the apartment we lived in, which I can recall in detail, and know when we lived there.
I just think it is because infants develop at different rates, and some possibly are born "older" than others. Some develop awareness earlier than others. I am not saying that means anything or doesn't equal out at some point.
Just the way it is.
