Most early childhood memories involve learning to ride a bike without stabilisers, or that magic moment when you suddenly work out how to tie shoelaces. Perhaps it was finding 20 pence under your pillow in the morning, deposited there by the tooth fairy.
Or maybe it involved trying to stay awake in the hope of catching a glimpse of Father Christmas. A quick straw poll of the people in my office revealed that the most common recollection was a feeling of insane jealousy when their younger sibling was born.
