What Is The Earliest Memory You Have From Childhood?

Mine is very vivid. I was around four years old, it was Christmas and I was in my footy jammies (yes, I said that). In the living room, the tree was all lit up and off to one side, circling the coffee table was a Lionel Train Track with a full set of train cars on it. I was so excited, got by the couch but had no idea how to start the thing. Mom flipped a switch and that distinct metal on metal sound started up, the train came streaming around the corner and I realized I was on the track, leaping up onto the couch behind me I watched in amazement as the train went whistling by scared and thrilled at the sight. Had some pics of that morning taken too and for a long time, I thought I was "remembering" it all from just those pics, but the memories I have are from my view point, not the pictures off to the side.

That's my earliest one. What's yours?

Will be back later to check, just thought I'd throw this out there. Hope you're all doing well today.
