On nervous systems, safety, and why some childhoods leave almost no trace
I was listening to my son remember everything about his own life. He impress me so many times hinting at some distant memory when he was about 2 or 5. The way I handed him food for breakfast on a random Tuesday. The exact words his grandpa said to him at his birthday when he was four.
I have almost none of that. Not from when I was his age, not from years after. Just fragments, and even those feel more like scenes I was told about than things I actually lived.
I used to think I just had a bad memory. It took me a long time to understand it was something else entirely.
What fight or flight actually does to a child
I grew up around people who argued often, whose moods shifted without warning. Nothing in my childhood would show up on a list of obvious harms. But there was a constant requirement to stay alert. To read the room before I walked into it. To sense a shift in tone before anyone said a word.
A nervous system that lives in that state isn’t idle. It’s working, constantly, just not on the things we assume childhood is for. When the body is monitoring for danger, actual or anticipated, it prioritizes threat detection over almost everything else. Memory formation, especially the rich, sensory kind that lets you replay a moment years later, needs a baseline of safety it can’t get if part of you is always scanning the room.
This isn’t a flaw in the child. It’s the nervous system doing exactly what it’s built to do. Survival first. Everything else, including the laying down of memories, waits its turn.
Why this isn’t about having a bad childhood
I want to be careful here, because it would be easy to turn this into a diagnosis of my parents, or a story about a childhood defined by horror. It wasn’t that. It was intense in ways that are harder to name, and harder to point to, than something a person could clearly identify as abuse.
A lot of us have had that. Life is not perfect. And that’s the part of what makes this pattern so easy to miss in ourselves. There’s no single event to blame. Just years of a body that learned, correctly, that it needed to stay ready.
What safety does that intensity never could
Watching my son remember things so easily isn’t just sweet to witness. It tells me something about the environment he’s growing up in, one where his body isn’t spending its resources on vigilance. Where the room doesn’t shift without warning. Where he can be fully in a moment because nothing in him is asking whether it’s safe to be there.
The work I’ve done on my own nervous system over these years wasn’t really about becoming a calmer person, even though that’s part of it. It was about giving my son a childhood his body can actually afford to remember. I won’t get mine back. And my own nervous system is shaped in ways I cannot truly change anymore.
He is, in a strange and lovely way, my own record of the past I can’t fully access. When he tells me about our trips, our ordinary days, the small things I’ve already lost, he’s handing me back pieces of a life I was there for but couldn’t hold onto. I’ll take that. Even if it comes through him instead of through me.
