Other commenters are trying to gaslight you into believing this isn't possible, but I also have a memory from before I could walk.

I was lying on the floor, contemplating a toy that had been hung above my head, when someone who was not one of my parents came to pick me up.

Years later, I told my mother about this. She then searched through the family film archive, and found the moment in question. The person who picked me up was my uncle.

This was not a film we had watched before, it came about because I was discussing with my mother our earliest memories.
