It depends, I think, although I'm not sure on what. I broke two bones through childhood misadventure, and I remember both those moments quite clearly. Likewise some of the particularly standout moments of bullying. And too, I spent a lot of time in the hospital as a small child, pretty much all of it unpleasant, and I remember that well enough.

But there are things I don't remember, too. There is enough continuous memory adjacent to such gaps that to infer what must lie within them is trivial, but it has to be inferred, because the memories themselves are either not present or not accessible.

There's nothing in those gaps to which I want or need access, so it doesn't concern me especially that I don't have it. But it does leave me able to attest that both responses not only exist, but can co-exist in the same person.

As I said, though, I really don't know what makes the difference in how memory and trauma interact, why it varies within and between people - certainly there are many who've had experiences like the ones I don't remember, only they do remember, and I wouldn't hazard a guess as to the why of either.

Not to suggest your experiences aren’t traumatic but it’s different when your parents/family hurt you emotionally, physically and otherwise. Also what is extremely traumatic for one person may not be as traumatic for another.

There's reason to expect that, too. Processing an event writes it more durably into the brain, and we have good reason to continue processing bad events until we have extracted whatever learning is possible from them.
