After their baby was killed by a car crash, parents aim to end road deaths

The Louis Thorold Foundation, set up by Rachael and Chris Thorold in memory of their son, campaigns for safer roads

Louis Thorold was just a perfect little baby, smiley and happy", recalls his father, Chris. One of the five-month-old's favourite toys was a plush elephant with crinkly ears. His mother, Rachael, remembers how relaxed Louis was, sleeping easily and even nodding off in her arms when she took him for weekly swimming lessons. We were so happy, we thought we had a lifetime of days like this ahead."

Yet for eight weeks after her son was killed in a road accident that left her with catastrophic injuries, Rachael had no memory that she had even had a child.
