About Billy Cart Behaviour

Why 'Billy Cart' Behaviour? Well, Billy Cart is a reference to two important people in Sarah's life who have made a significant impact to those around them. First is sweet Billy, who is a family friends son who sadly passed away at the young age of 4 months due to a genetic condition. The second person is bubbly and radiating Ashton Carter who is Sarah's godson, and has a genetic condition himself. Ashton is a light in the dark times, and someone who's laugh is so contagious that everyone smiles constantly when around him. These two young men have made an impact on Sarah's life and those important around us, that Sarah could not have thought of a better and more fitting name to dedicate to her life's work.

Billy Cart Behaviour is motivated to provide individualised behaviour support to clients using a positive behaviour support framework. So, what is Positive Behaviour Support? It is an evidence-based approach which considers an individuals environment, their support network, and current skill-sets which contribute to their overall quality of life. Secondary to improving an individuals quality of life, is decreasing challenging behaviours (both frequency and severity). We believe that everyone deserves to have access to the support and services that they need to life a rich and meaningful life. Billy Cart Behaviour endeavors to address the environmental 'mis-matches' which act as barriers, and develop alternative approaches or supports which can assist the individual to overcome such mis-matches.
