Three year old Megan Burgess died in 2008 while walking home from the shops in Meliden, Prestatyn. Last week a builder was jailed for two years for causing her death by not building the wall properly.
The court heard 49 year old George Collier from Kinmel Bay had failed to offer any protection for pedestrians passing the construction of the wall which was over 5ft in height and that it hadn't been anchored correctly.
Megan's Mother Lindsey is now calling for all construction workers to sign a register that homeowners can check before they sign them up to work on their property.
In an interview with Heart news Lindsey remembered how her little girl had been happily talking about baking cakes moments before she died. She also said Collier had attempted to resuscitate Meg at the scene but has since denied any responsibility for the three year olds death. Refusing to make eye contact with Meg's parents during the trial.
Lindsey says she hopes the campaign they're launching in memory of her daughter will not only make sure no family goes through a similar tragedy but also creates a legacy for the youngster. She is now working with politicians in both London and Cardiff to try and bring in the new law.
