Don't worry about forgetting your childhood memories

From getting lost in the supermarket to going on the rocking horse at playschool, memories from before the age of five are few and far between for most people. This is due to'childhood amnesia', which refers to the inability of people to remember anything from before the age of of around three and a half. During childhood, brains are more limber, which means they are able to absorb lots of information in a small space of time. However, parts of the brains that retain this information are still under construction, scientists say. From birth until our early teens, essential circuitry in the brain is still being laid down, as electric pathways become lined with fatty tissues to become more conductive, meaning we are able to retain these memories.
