First of all, sorry if this opens up some horrible old wound for anyone, that is not my intention :3 I'm just wondering what the INFPs' earliest memories are. If you wish, you could also note your Enneagram type and whether you think said memory had anything to do with the development of your Enneatype. As intuitives, we often wonder about the meanings of and connections between things, so if there's anything of that sort you want to throw in - go for it!
It's sad but my two earliest memories involve me crying. The first is just a seemingly random memory of me crying in my bed as a small kid. However, I think it may have been an indication of the sensitive guy I would become later on in life too. It's weird that I remember this specific cry but I do. I'm not sure what triggered it, but it was one of those cries that, looking back, feels like an "existential cry" (even though I was just a little child). Just bitter, void of hope, maybe even feeling some sort of strange emotional sensation of loss or abandonment (that is maybe where Enneagram 4 comes in).
The other very early memory I have is of my parents dancing together in the kitchen of my childhood house. They separated when I was very young, but in this particular memory, they must've been still together. The funny thing is, I was crying bitterly in that memory as well. I remember experiencing a strange mixture of emotions (especially for such a little kid!), kind of like "why is everyone else having fun and I'm not?" or something like that.
One of my first happy memories is of me, my cousin, my sister and our Dad getting to ride go-karts in an amusement park for free cos my Dad knew a guy who worked there. Fun times.
