The moment before Meg Burgess died, she and her mother Lindsay were walking back from the shops having bought sugar to bake cakes.
It was Lindsay's birthday weekend and instead of going away with a friend, as originally planned, she decided to stay at home with her daughter and the rest of the family.
Three-year-old Meg had been out with her father Peter, now 31, in the morning and had joined her mother later in the day. On the journey back from the shops in Meliden, near Prestatyn, the wall they were walking next to collapsed on top of Meg. She was taken to Glan Clwyd Hospital in Bodelwyddan but despite attempts to revive her she was pronounced dead after 10 minutes.
Lindsay told ITV Wales's Ian Lang that just before the incident happened she knelt down to Meg and told her, "You're the most beautiful thing."
This week a company director called George Collier was jailed for two years after being found guilty of manslaughter on the grounds of gross negligence.
Collier's company, Parcol Developments Ltd, had been hired to build the wall as part of renovation work on a cottage.
It took four years for Collier to stand trial after he denied the charges. The wait, Lindsay said, was difficult.
Lindsay and Peter now want to raise awareness of 'cowboy builders' and have set up a Facebook page Meg's Campaign where people can share their own experiences.
