My earliest memory is from when I was around 2-3 (I can't say for sure but it must have been early 3 at the latest). I was still in a crib, though I was close to switching to a twin bed. Anyways, I remember my mom put me down in the crib and gave me something to drink. When I had finished I tried to get apple juice but my mom would bring me other drinks (like milk) (I think we were out of apple juice). The memory consists mainly of my mom bringing me different drinks a couple of times, and I would lay down while I waited for her to come back.
I can't say it's a major memory but I know I was pretty young and I apparently really wanted apple juice.
As far as I know, I haven't changed all that much...
