Why don't you remember being a baby?

You lived an entire life before the age of three. You opened your eyes for the first time. You heard your mother's voice. You took your first steps. You experienced thousands of moments. And somehow, you remember almost none of them. Why? Scientists have discovered that infant memory is far more complicated than simply having an “underdeveloped brain.” Your hippocampus, rapidly growing neurons, developing sense of self, language, and even the culture you grew up in may all play a role in what survives. Your earliest memories weren't necessarily never created. Your brain may have been too busy becoming you to preserve the person you were before. So what actually happened to the first years of your life?
