Study makes 'baby amnesia' even more mysterious

New research sheds light on why adults don't remember being babies, but raises more questions than it answers

None of us remember being babies. In fact, most adults' earliest memories come from the age of about four and scientists don't really know why.

Researchers have long believed this phenomenon (called 'infantile amnesia') was because very young children didn't form memories of specific events while the part of the brain that dealt with memory, the hippocampus, was still developing.
