Why We Can't Remember Being a Baby?

追加: 2026-05-18

[00:00:00]Almost everyone has a memory from childhood. Maybe it's a birthday, a playground, a random moment that somehow stayed with you forever. But no matter how hard you try, you can't remember the beginning. Your first years are almost completely missing, which is weird when you think about it. Those were the years where you experienced everything for the first time. Your first laugh, your first fear, your first connection to another human being. So, where did all of it go?

[00:00:30]For a long time, people babies couldn't create memories, but scientists discovered that isn't true. Babies actually remember much more than we thought. Researchers placed babies in cribs with hanging toys. Babies learned moving their legs moved the toys. Days later, they repeated the behavior instantly, meaning they remembered the connection. So, the real mystery wasn't memory creation. It's why those memories disappear later. And the answer might be darker than people realize, because your brain wasn't failing, it was transforming. Inside your brain is the hippocampus. In adults, this system organizes long-term memories. It allows you to revisit moments from your life.

[00:01:16]But early in childhood, that system is incomplete. The brain is still wiring itself together. Connections are unstable. Storage systems are immature.

[00:01:27]But that's only part of the explanation.

[00:01:29]Neuroscientists later discovered something unexpected. During childhood, the brain creates huge numbers of neurons. Your brain is building the foundation of who you become. But there's a problem. New neurons can disrupt older connections, including the ones attached to memories. Researchers tested this idea in animals. Increased neuron growth caused worse memory retention. Slower neuron growth helped memories last longer. Your memories may have been erased by brain development itself. Your mind was expanding too aggressively for memories to survive, like rebuilding a city while people still live inside it. But memory loss goes deeper than biology. To create adult memories, you need identity, a sense that experiences are happening to you. Babies don't develop that immediately. Young children often don't recognize themselves in mirrors. At first, they think it's another person.

[00:02:30]Only later do they realize it's them.

[00:02:33]Without identity, experiences may never become personal stories. There's another missing ingredient, language. Before children learn to speak, experiences are mostly sensations, images, sounds, emotions, physical feelings. But language gives experiences structure.

[00:02:52]Children who talk about events preserve memories better. Words turn experiences into stories. Stories are easier for the brain to keep. Scientists found culture changes how far back people remember.

[00:03:06]Parents who tell stories help children remember earlier. Memory is shaped by conversation and storytelling. The reason you can't remember being a baby isn't simple. Your brain was still developing. New neurons kept rewriting old connections. Your identity hadn't fully formed yet. Language wasn't strong enough to preserve experiences.

[00:03:29]Everything was changing at once. And maybe that's the strangest part of all.

[00:03:34]The earliest version of you didn't disappear because it was unimportant. It disappeared so your brain could become who you are now.
