I believe that my earliest memory would be standing in a crib with wooden bar sides, looking down a long hallway that extended from the door to my room, and watching someone -- my Dad? I really have no idea except it was a man -- coming down the hall toward me. I was probably 2 at the time.
There's one that's even earlier, and it would have to be from infancy if it's an actual memory. All it is, is an impression of staring at something white with multi-colored spots on it very close to my face. The only reason I think it MIGHT be an actual memory, is that when I was only a couple of months old, somebody gave me a vinyl elephant. It was white, with small multi-colored dots all over it. (That elephant is still around somewhere, I think.)
