I had fragmented flash backs of being force fed food in a high chair with a plastic tray and screaming. I had no distinct memory just the odd flash of a choking sensation and the sound or sense of screaming and the plastic tray being there. I asked my Grandma about the way my Mother fed me as a baby and she verified that she had witnessed this and threatened my Mother with violence if she caught her doing it again. It added up with memories of force feeding and being threatened with being made to eat my own vomit at a later age when I was too big for a high chair. I believe that early memories can be repressed and surface as flashbacks that point to experienced trauma. As babies we don't make memories, but for sure our brains take snap shots of colours, sensations and sounds. I got all three, the colour of the tray, the sensation of food being rammed into my throat and the screaming being all around me. I have come to believe that a flashback is like a screenshot of a traumatic event, it doesn't have a narrative pattern the way a memory does, but they bubble up as a flash of colour sensation and sound given the right trigger. I asked my Grandma because my Mother and Father lived with her when I was a baby and I thought she might be able to shed some light on what I can best describe as a fragmented none memory of an event that felt like anguish and force feeding and sure enough she corroborated it. It might be helpful to talk to people who were around you at that age and see if anyone noticed anything unusual going on, it is surprising what others can recover for us when we encounter this sort of thing as a fragment of trauma. I have never recovered this memory specifically but Grandma was able to frame the context in which this flashback or snap shot was taken by my baby brain. I'm so sorry that you have had your experience negated.
