I remember sitting in a high chair and father tying a string to my spoon that had the loop for me to hold then everyone laughing when I threw it on the floor and it did not go to the floor but just hung over the side.
Probably around 1 year or earlier.

And I will go one further see if you think this is a true memory.
Whenever I was sick in my youth with a flu or something especially with an upset stomach I would wake up with big balls coming at me.
When I attended the birth of my oldest child and saw the doctor use the forceps to assist with the birth I remembered those balls coming at me when I was sick.

I expect all long term memories are tied to some unusual event and not the usual day to day happenings
