I remember my first brother coming home after being born. My mom said I could go in the room and look in the crib but not to say anything, he was sleeping. I leaned down and said his name - I was one and a half years old. I know this is a real memory as nobody was there, nobody told me this happened.

Then nothing I remember until my 3rd birthday, I remember the depressing zoo birthday, and then remember learning to read (sort of- I was 3 and memorized a short book, claimed I could read, but after that just could read, pretty much anything - so I don't remember the actual learning, however it happened, just that book, pretending to read it and that felt like it magically unlocked all books, it was remarkable and memorable).

That's about all my memories until 5 years old, but after 5 it's still just a few memories, even now I'd say just a few memories per year just a whole lot more years.
