I remember my parents leaving me in the hospital. I had a fit and was screaming. They put me in a crib with a top over because I tried to escape. I was 2 years old. Also I remember seeing the moon landing on TV that same year.
I can remember a few fuzzy memories from before age 4, but I usually don't know how old I was in those memories until a relative who was there can confirm it.
But back on point, my earliest memory is going to a fancy Italian restaurant for some sort of large family gathering. I was sitting at a huge round table with a lot of relatives all around. I had to sit on a booster seat to reach the table, and I ate a big plate of spaghetti and made a huge mess. I was 2 at the time.
