Why You Don't Remember Being a Baby?

Why don't you remember being a baby? It turns out infantile amnesia isn't what we were told — your infant brain was recording memories, and a 2025 Yale study scanning awake babies showed the hippocampus encoding them as early as your first year. So if the memories were made, why can't you reach them? This video breaks down the three forces that lock your earliest years away — and the one sense that can still crack the door open. We cover how memory encoding actually works in infancy, why the old "underdeveloped brain" theory was wrong, and how neural pruning, language, and your developing sense of self conspire to seal those years off. Plus: why smell is the one route that can briefly reach a memory you thought was gone forever. ▬▬▬ CHAPTERS ▬▬▬ 0:00 — The birthday you'll never remember 1:15 — What infantile amnesia really is 1:44 — The recorder theory (and why it was wrong) 2:23 — The Yale baby-scanning study 3:19 — Why it's a retrieval problem, not a recording one 3:57 — Force 1: the brain rebuilds its own map 4:40 — Force 2: memories with no language 5:23 — Force 3: the self under construction 6:21 — The memories became you 7:03 — The one sense that can reach back ▬▬▬ SOURCES ▬▬▬ • Yang et al., "Hippocampal encoding of memories in human infants," Science (2025).
