There are several probable reasons why we don’t remember our childhood
Do you, like me, have no memory of your life before the age of 3? If you try to recall your childhood, memories that surface are from the age of three or even later. And so the question arises: what was happening in your head during those first two and a half years? Why has the most powerful learning period of our lives — when we learned to walk, talk, and understand the world — vanished from memory as if it never existed?
What Is Childhood Amnesia
The fact that we don’t remember our infant years is such a widespread phenomenon that it has a scientific name — infantile amnesia. Psychologists have been grappling with this mystery for over a century, and no one can yet claim to have fully solved it. The authors of The Conversation covered this phenomenon in detail, and I’ve distilled the most useful information from it.
Why Don’t We Remember Childhood?
The first thing that comes to mind is that babies simply can’t form memories. But that’s not the case. Six-month-old babies are perfectly capable of forming both short-term and long-term memories. In a 1998 experiment, six-month-old infants learned to press a lever to start a toy train and remembered this skill for two to three weeks.
This creates a paradox: memory exists, but recollections don't.
We Forget Childhood as We Age
Our brain isn’t born fully developed. The region responsible for forming memories — the hippocampus — continues to develop until age seven. This explains one important detail: the boundary of childhood amnesia shifts with age. Children and teenagers remember themselves at earlier ages than adults do. Scientists believe the problem isn’t in creating memories, but in retaining them.
As Children, We Couldn’t Speak
Between the ages of one and six, a child goes from individual words to fluent speech. And this language leap perfectly overlaps with the period of childhood amnesia. Perhaps we don’t remember childhood because at that time we couldn’t talk.
A 2005 study confirms this. Scientists observed toddlers who ended up in emergency rooms with household injuries. Those who were older than 26 months and could describe what happened in words remembered it even five years later. Those who were younger and couldn’t verbally describe the event recalled nothing.
Adults Don’t Communicate Enough With Us
But the ability to speak alone isn’t enough. What matters more is how adults discuss the past with a child. When parents reminisce about events together with their toddler, they do something greater than simply sharing facts. They teach structure: what’s important, in what order to tell the story, and which emotions are tied to what.
The most striking example is the Māori people, the indigenous population of New Zealand. Their children remember themselves from an average age of two and a half — the earliest threshold among all studied societies. The secret lies in how Māori parents tell family stories: in detail, emotionally, with an emphasis on specifics.
Culture dictates its own rules. In countries that value independence (the USA, Europe), adults remember childhood earlier and in more detail than in cultures where community and connection with others come first (Asia, Africa). An American child will remember getting a gold star in kindergarten. A Chinese child will remember the whole class learning a song together.
Right now, scientists are using new methods: long-term studies where children are observed for years, and advances in neuroscience. This makes it possible to study memory not only through narratives but also through what’s happening in the brain.
