Yeah, yeah. In fact, actually, I was just talking to my really good friend and colleague, Simona Getty, who studies the neuroscience of child development. And so we were talking about this. And so there are a bunch of reasons, I would say. So one reason is there's an area of the brain called the hippocampus, which is very, very important for remembering events or episodic memory.

And so the first two years of life, there's a period called infantile amnesia. And then the next couple of years of life after that, there's a period called childhood amnesia. And the difference is that basically in the lab and even during childhood and afterwards, children basically don't have any episodic memories for those first two years.

The next two years, it's very fragmentary, and that's why they call it childhood amnesia. So there's some, but it's not much. So one reason is that the hippocampus is taking some time to develop, but another is the neocortex.

So the whole folded stuff of gray matter all around the hippocampus is developing so rapidly and changing, and a child's knowledge of the world is just massively being built up, right? So

I mean, I'm going to probably embarrass myself, but it's like if you showed like, you know, you trained a neural network and you give it like the first couple of patterns or something like that, and then you bombard it with another like, you know, year's worth of data, try to get back those first couple of patterns, right? It's like everything changes.

And so the brain is so plastic, the cortex is so plastic during that time, and we think that memories for events are very distributed across the brain. So imagine you're trying to get back that pattern of activity that happened during this one moment, But the roads that you would take to get there have been completely rerouted, right? So I think that's my best explanation.

The third explanation is a child's sense of self takes a while to develop. And so their experience of learning might be more learning what happened as opposed to having this first-person experience of, I remember I was there.

I wouldn't necessarily describe it as a trauma. We can get into this whole stages of life thing, which I just love. Basically, those first few years, there are, I mean, think about it, a kid's internal model of their body is changing, right? It's like just learning to move. I mean, if you ever have a baby, you'll know that the first three months, they're discovering their toes, right?
