Yes, very possible. I have no way of verifying the validity of my memory - if it was pre or post photo.

Your original question is an interesting one for sure. Now I have myself doubting whether my earliest memories are originals, or if they have been rewritten in my memory after flipping through a family photo album
I do have other mementos around that age though and no photos. Could also be figments of my imagination though!
Memories*
I think the human memory is rather tragic. We have so many great experiences throughout our life but many moments are just lost. It’s a great reason to be journaling semi-regularly. I should get back to that!
Reminded me to write down the day my 2nd son was born. I wrote a journal entry of my first, but not 2nd.
